MTH E-8 DIESEL ENGINE 
OPERATING INSTRUCTIONS 





Thank you for purchasing the MTH Electric Trains E-8 diesel locomotive. 
This 14” scale reproduction of the famous E-8 A-B-A locomotive consist 
measures over 55” in length and weighs over 11 pounds. Despite its scale 
size, the locomotive is capable of operating on O-31 3-rail track with any 
compatible AC transformer (see the chart on page 31 for a complete list of 
compatible transformers and wiring instructions) and is completely 
compatible with most other 3-rail locomotives, rolling stock and 
accessories. 


The locomotive is equipped with several deluxe features that are simple 
and fun to operate. Each feature is described among the following pages 
which should be read before the engine is operated. For those of you who 
can’t wait to get started, the Quick Start Basic Operating Instructions 
found on Pages 3 and 4 should be read so that you understand the basics of 
the operating system. Please note that some features are only found in the 
ProtoSound® models and are marked as such. Features not marked as 
ProtoSound features are available in all models.

E8 Operating Manual 


QUICK START - BASIC OPERATION 


The MTH E-8 contains state-of-the art electronics with several built-in 
automatic features for incredibly realistic operation. Despite these advanced 
features, the E-8 is easy to operate with any compatible standard AC 
transformer (see the compatibility chart on page 31). All models are 
equipped with an operating smoke system that should be primed with 
smoke fluid before operating. Adding 20 - 25 drops of fluid through the 
smoke stack should be sufficient. (See Figure la). If you choose to not 
prime the smoke unit(s) with fluid, turn the smoke unit switch located 
under the rear drive truck(s) to the eee 
OFF position. (See Figure 1b). T 
This will prevent any damage from 
occurring to the smoke unit when 4 
the engine is running without a 
primed smoke unit. For more 
information see the section on Page 
4 on smoke unit operation. 






Figure la: Adding Smoke Fluid to the Smoke Unit 


The E-8 locomotive is controlled BrotoGouper 
by a ProtoSound® DCRU® 
electronic reverse unit. The reverse 
unit operates in the same manner 
that all reverse units function by 
using forward, neutral and reverse ae 
states that are entered each time the Figure 1b: Locating The Smoke Unit & ProtoCoupler 
throttle is turned on and off or by Selection Switch 
using the transformer direction 
switch (if so equipped).

short circuits without disrupting the engine 
operation, even at slow, prototypical 
speeds. Once the engine is placed on the 
track, the throttle on the transformer can be advanced. You will see that 
only the engine’s lights come on and that only two dings of the ProtoSound 
bell occur followed by the diesel start-up sounds (on ProtoSound equipped 
3-rail models). The engine does not run. This is known as the RESET state 
and is explained in more detail beginning on Page 4. The ProtoSound® 


DCRU® will not power the motors until the throttle is turned OFF and then 


Figure 2: DCRU™ Cycle Phases 


3 
E8 Operating Manual 


ON again. At this point, the engine will now function just like any other 
electronic or mechanical E-unit. 


PROTOSMOKE™ UNIT OPERATION 


The E-8 contains a self-powered smoke unit that outputs a steady stream of smoke through 
the smoke stack on the roof of the engine. The ON/OFF switch located next to the power truck 
must be in the ON position in order for the smoke unit to function. See Fig. 1 on page 3. 


The smoke unit is essentially a small heating element and wick which soaks up and then 
“cooks" a mineral oil-based fluid that omits a harmless smoke. The smoke is then forced out 
of the stack via a small electric fan which runs at a constant speed. However, the smoke 
intensity can be varied by increasing the transformer voltage setting. The higher the setting, 
the more intense the smoke output. 


For best results, we recommend that you add 20 - 25 drops of ProtoSmoke™, Seuthe, LGB or 
LVTS fluid before you run the engine. If you don’t choose to add the fluid, then the smoke 
unit switch should be turned off. Failure to either add the fluid or turn the switch off could 
lead to damage to the smoke unit heating element and or wicking. Add the fluid through the 
smoke stack hole. After adding the fluid, gently blow into the stack to eliminate any air 
bubbles. Do not overfill the unit as overfilling can cause the fluid to leak out and coat the 
interior engine components. When the smoke output begins to diminish while running the 
engine, an additional 20-25 drops of smoke fluid should be added or the smoke unit switch 
should be turned off. When storing the engine for long periods of time, you may want to add at 
least 20 drops of fluid to keep the wick soaked with fluid and prevent it from drying out. After 
removing the engine from storage, it is advisable to add another 25 drops of fluid, letting the 
wick soak up the fluid for 15 minutes 
prior to operation.

MAINTENANCE 


After Removing 
Mounting Screws,

CAUTION: Operating the engine Smoke Unit 
without smoke fluid and with the smoke Circuit Board 
unit switch in the ON position can Mounting Serews 
damage your smoke unit wick, causing 
the wick to become hard, blackened and 
unabsorbant around the heating element. 
When this occurs, it may be difficult for 
the wick to soak up the smoke fluid 
resulting in poor or no smoke output. If 
that occurs, we recommend that you 
inspect and/or replace the wick taking 
care to not run the engine without fluid in 
the future. You can inspect the wick to 
see if it needs replacement by removing Figure 2: Inspecting The Smoke Unit Wicking 

the smoke unit circuit board from the 

smoke unit body as seen in Fig.2. After 

removing the circuit board screws lift the circuit board away and inspect the wick. If the wick 
is darkly discolored and hard, it should be replaced.

PROTOSOUNDS ® INSTRUCTIONS 


The MTH ProtoSound® digital sound and train control system provides 
the operator with unprecedented realistic operation on your model railroad. 
In addition to actual diesel engine, CD-equivalent 16-bit digital sounds, 
you get the following features: 


* Built-In DCRU Reverse Unit * Authentic Diesel Engine Horn Sound * 
Authentic Diesel Engine Bell Sound * Squeaking Brake SoundFreight Yard 
Sounds * Operating Remote Controlled ProtoCoupler™ * Self-Recharging 
Battery Back-Up System With Automatic Battery Shut-Off * Remotely 
Controlled Reverse Unit Lock-Out * Remotely Adjustable Diesel Engine Volume 


* Upgradeable Microprocessor Options * Authentic Diesel Engine Start Up & 
Shut Down Sounds * Random Selection of Four “Cab Chatter" Radio 
Transmission Sound Clips * Authentic Diesel Shut Down Sounds 


Each feature is described among the following pages. Though the system 
is easy to use, we encourage you to read the instructions thoroughly. 


PROTOSOUND® DCRU® REVERSE UNIT 


As mentioned in the Basic Operating section, the engine is controlled by a 
ProtoSound® DCRU® reverse unit that contains the standard 
forward-neutral-reverse states found on most reverse units. However, as 
described earlier, when power is first applied to the track, the reverse unit 
begins in RESET or what seems like a neutral state. Power must be 
interrupted again to get the locomotive to enter the forward state. It is this 
first RESET state that gives ProtoSound® its unique, remote controlled 
functions. The system will enter RESET whenever power to the track is off 
for three or more seconds. NEUTRAL will be referred to as the state 
between Forward and Reverse. 


ProtoSounds® is equipped with a microprocessor, that, depending on the 
amount of memory it is allotted, allows the user to utilize several remotely 
activated functions. In the simplest terms, ProtoSounds® has its own 
“Computer” controlling these functions. In fact, the power of this 
microprocessor is the same as that of a 286 desktop computer! In order to 
access many of these remotely controlled functions, the user must be in the 
RESET state to do so. RESET is entered anytime power to the locomotive 
has been off for more than 3 to 5 seconds. When the engine first enters 
RESET, the microprocessor initiates a system check to determine if the 
system, transformer and engine are operating correctly. This takes 


5 
E8 Operating Manual 


approximately 2.2 seconds during which you will hear the engine’s startup 
sounds begin. In order for ProtoSounds to properly initiate the system 
check, do not advance the transformer throttle past 10 volts when you first 
enter RESET, wait for the diesel startup sounds to begin and then slowly 
turn the transformer throttle to the off position and then back on again to 
enter the forward phase. Interrupting the power too quickly may cause the 
system to re-enter RESET (signaled by two dings of the bell). Should this 
happen, wait longer before interrupting the power to enter the Forward 
phase. 


ProtoSounds® comes with several programmable functions, including 
Engine Volume Adjustment, Separate Bell Button Operation 
(pre-programmed at the factory), Cab Chatter On/Off Control, ProtoCoupler 
On/Off Control and Horn-In-Neutral Operation. Each of these features are 
described in more detail later. You will notice that when in RESET, your 
engine will not respond to the whistle button with a horn blast or continuous 
bell ringing. In fact, when in RESET and the whistle button is depressed, 
only one single bell chime will be heard each time the whistle button is 
pressed. If you don’t want to configure or change your locomotive using 
any of these programmable features, simply leave RESET and wait 2.2 
seconds before interrupting the power to put the engine in forward. After 
you leave RESET, your engine will operate normally in all the direction 
states of forward, neutral and reverse. 


HORN OPERATION 


Your MTH E-8 ProtoSound-equipped engine is equipped with a digital 
recording of a diesel horn. The horn sound can be activated anytime the 
engine is in forward or reverse by pressing the whistle button on your 
transformer. The horn will continue to blow as long as the whistle button is 
depressed. The horn will not function in RESET and must be configured 
through a RESET option to allow the horn to work when the engine is in 
neutral. See page 19 for information on horn programming in the Using 
RESET To Program ProtoSounds® section of this manual. 


BELL OPERATION 


Your MTH E-8 ProtoSound-equipped engine is equipped with a digital 
recording of an actual diesel bell. Unlike previous versions of ProtoSounds, 
the bell can be turned on or off with any separate bell button, like the 
Lionel® Railsounds® No. 5906 Bell Button, by simply pushing the button. 


6 
E8 Operating Manual 


If you don’t have a separate bell button, the bell can be controlled through 
your transformer’s whistle button whenever the engine is in NEUTRAL. 
The bell will never ring continuously in RESET (Remember NEUTRAL is 
the state between Forward and Reverse). Once the bell is turned on, it will 
continue to ring when the engine is cycled into forward or reverse until you 
press the bell button or re-enter NEUTRAL and turn the bell off with the 
whistle button. 


In fact, because of ProtoSounds® state-of-the-art design, the 
microprocessor remembers its last command. Therefore, unless you turn 
the bell off before you quit running your train, the next time you run the 
engine, the bell will come on. No matter whether you come back an hour 
later or a year later, the bell will begin chiming once the engine enters one 
of the three directional states. 


To turn the bell on using the transformer’s whistle button, turn on power to 
the track and cycle the engine into NEUTRAL. Turn the throttle to 8 volts 
or less (any higher voltage will arm the ProtoCoupler) and press the whistle 
button. The bell should begin chiming. To turn the bell off, press the 
whistle button again. If you want to keep the bell on while running the 
engine, simply interrupt the power with the transformer throttle or the 
transformer directional switch and enter forward or reverse. 


PROTO-COUPLER™ OPERATION 


Your MTH E-8 ProtoSound-equipped locomotive has two coil-wound 
ProtoCouplers™ for remote uncoupling action. The couplers are mounted 
on the power trucks. Because the ProtoCoupler is controlled through 
ProtoSound’s microprocessor, it doesn’t require an uncoupling track section 
or modification to your layout to function. The three simple steps below 
are required to operate the coupler. 


1. Put your engine in NEUTRAL and turn the throttle all the way up. 
2. Press the transformer whistle button to “Arm" the coupler. (You 
will hear a “Clank") 

3. After arming the coupler, press the whistle button again to open 
the coupler.

apart. It can best be described as a CHA-CHUSHHH sound. The coupler 
doesn’t have to be fired in NEUTRAL. Once the coupler is armed it can be 
fired in Forward, Neutral or Reverse. However, you may find that the 
coupler doesn’t open when 
firing the coupler at high 
speeds. Reduce the voltage 
setting on your transformer if 
this occurs and run your engine a 
at a slower speed before firing Ln o 
the coupler. If the coupler eee 
continues to open erratically, try 
lubricating the knuckle with 
light oil as indicated in Fig. 3. 





Figure 3: Lubricating The ProtoCoupler Knuckle 


For multiple heading purposes, only one of the two Proto-Couplers will 
function at any one time. Use the coupler direction switch as shown in Fig. 
1 on page 3 to select either the front or rear coupler. Simply slide the 
switch toward the direction of the coupler you want to make active. 


NEUTRAL-ACTIVATED CAB CHATTER SOUNDS 


Whenever your diesel locomotive is parked in Neutral randomly played 
“Cab Chatter” sound effects will occur every 2 to 30 seconds. There are a 
total of four of these Cab Chatter sequences that capture authentic radio 
transmissions between dispatcher and engineer. They are designed to play 
at random intervals to eliminate repetitive and boring sequences though 
there is no guarantee that you won’t hear the same message repeated two or 
more times.. 


SQUEAKING BRAKE SOUNDS 


Proto-Sound® equipped engines feature the ability to play the sound of 
squeaking brakes whenever your engine slows in speed. There are two 
settings for activating the squeaking brake sounds. The default setting 
allows the brake sounds to play while the engine is in forward or reverse 
and the transformer throttle is lowered from a high setting to a low setting 
(14 volts to 8 volts or less). The 


sound itself is a stored recording Throttle Down From Saied a Broke Sodi dė

E8 Operating Manual 


voltage is reduced from high to low. Some practice may be required to 
synchronize the playing of the brake sounds with the movement of the 
engine. It is not uncommon for the engine to stop before the brake sound is 
completed. Operators will find that coordinating the movement of the 
throttle setting from 8 volts to off will allow the engine to maintain its 
movement while the brake sounds play. Note: The brake sounds will not 
be heard if the transformer throttle is not set above 14 volts and/or not 
reduced below 8 volts. 


TIPS ON USING THE SQUEAKING BRAKE FEATURE 


Users will find the squeaking brake feature to be a very realistic way 
to simulate the sound of an engine slowing down for curves, crossings 
or coming to a stop at a station, side track or switch yard. However, 
you may find that your engine continues to play the brake sounds once 
your engine comes to a stop, or that the sounds stop before the engine 
comes to a complete halt. For example, if you simply run the engine 
and turn the throttle off quickly, the brake sounds will likely continue 
playing even though the engine has come to a complete stop. 


This annoying effect can be eliminated by simply practicing with the 
brake feature. In no time, you will quickly learn how to “feather" the 
throttle to keep the engine moving while the brake sounds play and 
then turning the throttle off just as the sounds stop.

Operating Proto-Sound® Passenger Station 
Sound Effects 


Passenger Station Announcements (PFA) 


Proto-Sound® is equipped with operator controlled Passenger Station 
Sounds, referred to as PFA. The PFA sequence is designed to simulate 
the arrival, disembarking, embarking and departure of a passenger train 
in a Passenger Station. This easy-to-use feature allows you to play 
digitally recorded sounds of Passenger Station sounds while your 
engine is parked in the Neutral State. No additional wires or 
modifications are needed to enjoy these amazing sound effects. The 
sounds themselves are randomly “shuffled” by the Proto-Sound® 
computer. This gives the system the ability to play the various sounds 
in a different order each time PFA is enabled.

Activating Passenger Sounds (PFA)- Detailed PFA 
Instructions 


Arming The Passenger Sounds Feature 


Before the Passenger Station sounds can be heard, the feature must be 
activated. The feature can be activated in one of two ways. 


Option 1: If you are using the Z-4000™ transformer, or any transformer 
with a separate bell button controller, you can activate the feature by simply 
pressing and holding the bell button for at least three seconds (it does not 
matter if you are in forward, neutral or reverse). You will hear the bell turn

the bell button. If you were in neutral, interrupt the transformer throttle to 
enter the next directional state (either forward or reverse). (Note: the PFA 
will only play in the first Neutral after it is armed. You can not interrupt 
the power twice to enter another direction and still have the PFA active.) 
You can now trigger the sounds to begin playing when you next enter 
Neutral. 


Option 2 If you do not have a separate Z-4000™ transformer (or separate 
bell button available), you can activate the PFA using your transformer’ s 
whistle button control. To arm the PFA, turn on the transformer throttle and 
cycle your engine into

to chime, so if you want to turn off the bell ringing, simply press and release 
the whistle button. Interrupt the transformer throttle to enter the next 
directional state (either forward or reverse). (Note: the PFA will only play 
in the first Neutral after it is armed. You can not interrupt the power 
twice to enter another direction and still have the PFA active.) You can 
now trigger the sounds to begin playing when you next enter Neutral. 


TRIGGERING PASSENGER STATION 
ANNOUNCEMENTS 


Once the PFA feature has been activated, it will be played the next time 
the engine enters neutral. At this point, Proto-Sound® will take over 
control of your engine, disabling the bell and whistle button. In addition, 
Proto-Sound® reconfigures the way the reverse unit functions during the 
operation of the PFA feature. This forces the engine to leave your 
Passenger Station in the same direction as it arrived. The following 
operator controlled “Events” control the PFA’s actions and sounds. (Note: 
The direction states shown assume the PFA is entered from forward. If 
entering the Passenger Station in reverse, the direction states shown will 
be reversed.) 


Event 1: Interrupt the transformer throttle to cycle the engine from forward 
into neutral. If the throttle was at 14 volts or higher, the squeaking brakes 
sound will play. Once the engine is stopped, the throttle 

must be turned on to keep it in the 

neutral state. Note: Failure to turn the —“stfowpower—“anaGas Chater Meose” 
throttle back on within 3 seconds of PAN S 
leaving forward will disable PFA and E é 
shutdown Proto-Sound®. The next 
time power is turned on, the engine 
will be in the RESET position. See 
page 23 for additional information on RESET. If the bell was not turned 
off after arming PFA, it is now turned off automatically. After entering 
neutral, Proto-Sound® will immediately play a horn blast or an air release 
sound, followed approximately 2 seconds later by an Arrival 
Announcement. Following this arrival announcement, the sounds of doors 
opening and the conductor saying “Watch your step” is heard. At this point, 
various Passenger Station sounds can be heard, including passenger 
footsteps, muffled voices, baggage being moved about and whistling for a

conductor saying “Baggage to the 
right/left.” Once this highlight is played, the Passenger Station sounds 
heard in Event 1 will continue to play.

passenger car door closing. Within two seconds, the whistle will sound two 
short blasts (three if entering reverse), and the bell will begin to chime. 
After a few chimes of the bell, the engine will begin moving in forward

E8 Operating Manual 


TIPS ON USING THE PFA FEATURES 


PFA is a unique feature of Proto-Sound® that is completely controlled by the 
operator. You decide how, when or if you want to utilize the feature. By 
reviewing the following tips, you should find solutions or suggestions to the 
various operating scenarios you might encounter when using PFA. 


Tip #1: You can escape the PFA sequence by interrupting the transformer 
throttle before the man’s whistle plays in Event 1 (neutral). 


Tip #2: You can exit PFA at anytime by turning the transformer throttle Off for 
15 seconds. 


Tip #3: You do not have to be in Forward to utilize PFA. For example, if you 


activate the PFA feature while in Reverse, your train will leave the station/yard 
in the same reverse direction that it arrived in. 


Tip #4: You can use PFA even if you are double-heading with another engine 
regardless of whether the second engine is equipped with an PFA programmed 
Proto-Sound® module. If the second engine isn’t equipped with PFA, the only 
thing to remember is that you not to turn up the transformer throttle very high 
when entering Reverse in Event 2. If the throttle is set too high, then the second 
locomotive will begin vibrating on the track as its motors will be turning in 
reverse. If your second engine is equipped with PFA, you may want to disable 
the PFA when used in double-headed operations. To disable PFA, see the 
section on programming RESET functions on page 26 of this manual. 


Tip #5: You can leave any of the event stages at any time by simply 
interrupting the transformer throttle. Any sound effects programmed to play in 
that event will simply not occur. The only exceptions are Event 1 and Event 4. 
In Event 1, interrupting the throttle has no effect on PFA until after the man’s 
whistle has completed and the freight car doors have opened. In Event 4, you 
cannot interrupt PFA until after the engine begins to move. Interrupting the 
throttle before the engine begins to move has no effect on the locomotive’s 
operation.

Special Reverse Unit Options 


Reverse Unit Lockout Operation 


For operators who wish to lock their engine into a single direction, 
Proto-Sound’s® unique design eliminates the need for a lock-out switch 
on the locomotive. This will allow users to run the engine on layouts 
equipped with block signals or stop stations that would normally cycle the 
engine back into neutral. Note: The feature must be first turned on by 
accessing RESET Feature 40 (See page 22). 


Locking the Engine into Single Direction Operation 


Cycle the transformer throttle so that your engine is operating in the 
direction you wish to lock it in (forward, neutral or reverse). With the 
throttle set to approximately 8 volts, press and hold the horn/whistle 
button. While holding the horn/whistle button, turn the throttle OFF, and 
then release the horn/whistle button. After 2 seconds, you will hear a short 
horn blast. IMMEDIATELY turn the throttle back on. The engine is now 
locked, and will continue in the previous direction whenever power is 
applied to the track. 


Unlocking The Engine 


With the throttle set to approximately 8 volts, press and hold the 
horn/whistle button. While holding the horn/whistle button, turn the 
throttle OFF, and then release the horn/whistle button. After three 
seconds, a single bell will be heard indicating that the engine is unlocked. 
When power is again applied, the engine will enter RESET and perform as 
normal. 


NOTE: When locking the engine in the Forward or Reverse positions, the 
horn/whistle button will blow the horn/whistle. But when locking the 
engine into the NEUTRAL position, the horn/whistle button may turn on or 
off sounds of the bell. Remember, the horn/whistle doesn’t blow in 
NEUTRAL (unless you programmed it to do so using Reset Feature 25 - 
see page 25 for details), only the bell rings.

E8 Operating Manual 


SELF-CHARGING BATTERY BACKUP 


Proto-Sound® includes a self-charging battery backup system for improved 
performance at any speed. The battery ensures that power to the sound 
system will remain on during directional changes, while setting RESET 
options or when traveling over spots of dirty track and switches. The 
self-recharging battery backup system is automatically turned on or off. 
There no switches needed to enjoy the benefits of the automatic battery 
backup system. 


Proto-Sound® contains a warning alarm if the battery backup system fails 
to automatically disengage when track power is turned off. Should the 
backup system fail, you will hear a repeating whistle blast indicating that 
this has occurred. Should this happen, unplug the battery from the 
Proto-Sound® module (to prevent the battery from being run down) and 
contact MTH for instructions on returning the train for repair.. 


REPLACING THE PROTOSOUND BATTERY 


The Proto-Sound® battery (located in the tender body), is a special NiCad 
7-cell, 8.4v battery -NOT the 6-cell, 7.2v battery found in most convenience 
stores. The battery is continually charged from the track when power is 
applied above 11 volts. Should last for up to five years. In addition, the 
NiCad battery is a dry battery and should not leak or cause any damage to 
your locomotive during its lifetime. The 6-cell NiCad is NOT 
recommended for use with Proto-Sound® applications. 


If you notice that the sounds seem distorted or garbled at low voltages or 
become immediately silent when power from the transformer is shut off, the 
battery may be failing. Before replacing the battery, you should put the 
engine in NEUTRAL and leave the transformer throttle set at about 12 volts 
for 15 minutes. This should temporarily recharge the battery. If the garbled 
or distorted sounds are reduced, then your battery charge has worn down. 
You can give your battery a full charge by leaving the engine ON in the 
NEUTRAL position for 6 hours. 


Note: When charging the battery in neutral, if your trains contains a 
Smoke Unit should be turned OFF to prevent damage to the wick and the 
heating elements. 


17 
E8 Operating Manual 


If you need to replace the battery, they are available from MTH 
Proto-Sound® Electronics at 7020 Columbia Gateway Drive, Columbia, 
MD 21046-1532. A standard 9v alkaline battery can be substituted as a 
temporary fix, but, since alkaline batteries can’t take a charge, it will 
eventually wear down. 


MANUALLY ADJUSTING THE PROTO-SOUND® 
VOLUME 


Your Proto-Sound® system has two types of volume adjustment. A manual 
turn knob on the bottom of the chassis (See Fig. 4 below) allows you to 
control all the sounds in the system and a remote control “RESET" option 
(Option # 6) allows you to control the volume level of the engine sounds 
remotely from the transformer. Turning the volume adjustment knob one 
direction will increase the volume. Turning it the opposite directions will 
lower the volume of all sounds: bell, horn, engine sounds, Cab Chatter, etc. 
For information on operating the RESET volume adjustment option, see the 
section entitled “Programming Proto-Sound® RESET Options” on the 
following pages

USING “RESET" TO PROGRAM 
PROTOSOUNDS® 


ProtoSound® is equipped with several programmable features which are 
accessed in the RESET state by moving the transformer throttle up and 
down between full voltage and low voltage (8 volts) without shutting the 
transformer off completely. Each time this is done you advance, one 
feature at a time, through the available options. An air-release sound is 
heard each time the throttle is advanced and returned. In addition, there are 
special sounds to tell you 
what RESET position you In RESET Mode

engine in RESET, and 
move the throttle up and

low two times. After the second advance, you will hear two “clinks" 
indicating that the computer is now in Feature 2. Advance the throttle again 
and you will hear three “clinks" for Feature 3. Advance it two more times 
and you will hear a “clank" indicating that you are now in Feature 5. 
Advance the throttle two more times and you will hear a “clank" and two 
“clinks" indicating Feature 7. ((5 throttle advancements = 1 clank) + (2 
throttle advancements = 2 clinks)). “Clank” + “Clink” + “Clink" = Feature 
7. You can advance the throttle as quickly as you like (though you may not 
hear the air-release sounds) and the computer will still remember the 
number of times the throttle is advanced by playing back the number of 
“Clinks" and “Clanks" to confirm the feature you’ ve selected.

OIL & LUBRICATION INSTRUCTIONS 


In order for the engine to perform correctly and quietly, it is important that 
the chassis be lubricated before operation. Lubrication should include all 
truck block bushings and pickup rollers to prevent them from squeaking. 
Use light household oil and follow the lubrication points marked “L" in Fig. 
7 below. 






Lubricate 


Lubricate 
Figure 7: Lubricating The Truck 


The locomotive’s internal gearing in both power trucks has been greased at 
the factory and shouldn’t need additional grease until after 50 hours of 
operation or one year whichever comes first. Grease cannot be added to the 
internal gearing until the body is removed from the chassis which is held in 
place by four Phillips screws. The screws are located on each end of the 
chassis’ as seen in Fig. 9 on the following page. After removing the screws, 
lift the body away from the chassis and lay the body next to the chassis. 





Grease 
Figure 8: Greasing The Power Trucks 


24 
E8 Operating Manual 


Next, remove the truck blocks from the chassis by unscrewing the large 
Phillips motor mount screw on the bottom of each truck block (See Fig. 8). 
Once the motor mount screw has been removed, pull the motor away from 
the truck block and lightly coat the motor worm gear and bronze drive gear 
(in the truck block) with grease. Reassemble the truck and motor, being 
careful not to pinch the pickup and ground wires between the truck block 
and motor mount. Repeat the procedure for the other motor and truck and 
then reassemble the chassis to the body. When reassembling the chassis and 
body, be very careful that the lighting wire harnesses are not caught 
between the body and chassis as this can lead to a short which may damage 
the electronic circuit boards beyond repair. 


In addition to the truck block internal gearing, it is a good idea to lubricate 
the outside truck block “idler” and “drive" gears with grease. Use the 
diagram shown in Fig. 7. above as a guide and add grease to the points 
marked with a “G". 


Periodically, check the locomotive wheels and pickups for dirt buildup as 
this can significantly affect the engine’s ability to perform properly. Dirty 
track and dirty wheels can cause both poor electrical contact as well as poor 
traction, especially on elevated track sections. Finally, dirt and oil build up 
can prematurely wear out the neoprene traction tires. 


TRACTION TIRE REPLACEMENT 
INSTRUCTIONS 


Your locomotive is equipped with two neoprene rubber traction tires on 
each power truck. While these tires are extremely durable and long-lasting 
there may arise a time where they will need to be replaced. Should this 
occur, you will need to remove the trucks and truck sides on the truck block 
from the chassis in order to slip the new tire over the grooved drive wheel. 






mr Coe 


Body Mount Screws 


25 
E8 Operating Manual 


We suggest you follow the disassembly instructions found in the 
Lubrication section on the preceding pages to dissemble the chassis and 
truck blocks from the body. 


Before the new tire can be installed, you must make sure the old tire has 
been completely removed from the groove in the drive wheel. Use a razor 
blade or small flatblade screwdriver pry away any remains left from the old 
tire that may still be in the drive wheel groove. Once the old tire has been 
completely removed, slip the new tire onto the wheel. You may find it 
useful to use two small flatblade screwdrivers to assist you in stretching the 
tire over the wheel. Be careful to avoid twisting the tire when stretching it 
over the wheel. If a twist occurs, the tire will have to be removed and 
reinstalled or a noticeable wobble in your engine will occur when operating 
the locomotive. In addition, it is important to make sure that the tire is 
fully seated inside the groove. Any portion of the tire extending out of the 
groove can cause the engine to wobble. A razor blade can be used to trim 
away any excess tire that doesn’t seat itself inside the groove properly. 


Once the new tire(s) are in place, reassemble the truck sides to the truck 
blocks and then reassemble the chassis to the body. Replacement tires are 
available directly from MTH Electric Trains. 


HEADLIGHT REPLACEMENT 


The E-8 locomotive’s headlights are controlled by constant voltage circuits 
inside the locomotive body. The headlight(s) can be easily removed from 
their lampholders should the bulbs expire. To remove the bulb, follow the 
body removal instructions found in the Lubrication section on the 
proceeding pages. Once the cab has been separated from the chassis, gently 
unplug the bulb’s wiring harness from the socket on the constant voltage 
circuit. Replacement bulbs are available directly from MTH Electric 
Trains.

TROUBLE SHOOTING PROTOSOUND® 


PROBLEMS 


Although ProtoSound® has been designed and engineered for ease of use, 
some questions may arise during initial operation. The following table 


should answer most questions. If you find that your problem can’t be 
resolved with this manual, contact MTH ProtoSound Electronics (7020 
Columbia Gateway Drive, Columbia, MD 21046, 410-381-2580) for 


additional assistance. 


HORN PROBLEMS 


REMEDY 


The horn seems distorted at low voltages. 


Your battery may be undercharged or dead. Try 
recharging the battery as explained in the battery 


sections. 





When | press the whistle button, the bell comes on 
instead. 


You are trying to operate the horn in neutral. The horn 
will only operate in Forward or Reverse unless you 
program ProtoSounds through Feature 25. See the 
instructions in the section entitled “Using RESET to 
Program ProtoSounds”. 





| can’t get the horn to blow when | press the whistle 
button. 


When | press the whistle button to activate the bell, the 
horn sounds. 


You may be pressing the whistle button too quickly. 
Most older AC transformers contain a two--step whistle 
button that releases a DC signal onto the track. It is 
this DC signal that tells the horn to blow. However, 
because the signal is weaker when the whistle button 

is depressed fully, the ProtoSound circuit may not 
recognize the signal. Try pressing the whistle button 
slower, taking approximately 1 second to fully depress 
the button. 


BELL PROBLEMS REMEDY 


You are trying to ring the bell in Forward or Reverse. 
The bell only operates in Neutral unless you have 
programmed ProtoSounds to recognize a separate bell 
button. 





When | press the whistle button to activate the bell, | 
arm the coupler. 


Reduce the voltage on the transformer before pressing 
the whistle button to activate the bell. The bell will only 
come on at 8 volts or less. 





When | press the whistle button to activate the bell, the 
bell only rings once. 


You are trying to ring the bell in RESET instead of 
neutral. Interrupt the power twice to enter Neutral, set 
the voltage at 8 volts or less and press the whistle 
button to activate the bell. 





| can’t get the bell to ring when I press the whistle 
button. 


You may be pressing the whistle button too quickly. 
See the 3rd remedy in the horn section above. 





The bell won’t work with a separate bell button. 








ProtoSounds must be programmed in order for a 
separate bell button to function. Enter RESET function 
number 20 (see the section entitled “Using RESET to 
Program ProtoSounds”) and press the whistle button 
until the bell sounds two dings. Simply turn the throttle 
off and then on again to lock in the new setting. 


27 


E8 Operating Manual 





COUPLER PROBLEMS 


REMEDY 


The ProtoCoupler won't let the engine uncouple on the 
“Fly”. 


The power required to fire the coupler open when the 
engine is on the “Fly” may be greater than the 
ProtoSound system is capable of providing. As a 
result, you may experience times when the coupler 
won't fire open. Unfortunately, the only solution is to 
stop the engine and fire the coupler in Neutral. If that 
doesn’t resolve the problem, try lubricating the coupler 
knuckle and rivet as explained in the ProtoCoupler 
Operation section. 





| can’t get the coupler to arm or fire open when | press 
the whistle button. 


You may be pressing the whistle button too quickly. 
See the third remedy in the horn section above. 
Another possibility is that ProtoSounds has been 
programmed to turn the coupler function off. See the 
section entitled “Using RESET to Program 
ProtoSounds” 





Only one coupler will function when | press the whistle 
button. 


DIESEL START/CAB CHATTER 


Only one coupler can operate at any one time. Use 
the coupler selection switch on the bottom of the 
chassis to choose which coupler you want active. 


REMEDY 


Sometimes the diesel start sounds don’t occur when | 
first turn power on. 


Occasionally the diesel engine start up sounds may 
not occur when power is turned back on within 5 
seconds of being shut off. Wait 10 -- 15 seconds 
before repowering. 





Sometimes the Cab Chatter sounds don’t play. 


LOCKOUT PROBLEMS 


The Cab Chatter sounds only play in neutral and 
ProtoSounds may be programmed to turn thesounds 
off. See the section entitled “Using RESET to 
Program ProtoSounds” 


REMEDY 


| can’t get the engine to run after | power up the 
transformer. It sits still with the diesel compressor 
sounds running. 


The engine is locked out into the Neutral position. 
Follow the unlocking procedures in the Lockout 
Section. 





The engine won't lock out into Forward, Neutral or 
Reverse even after the short horn blast sounds. 


VOLUME PROBLEMS 


You are waiting too long to turn the throttle back on 
after the short horn blast sounds. The power must be 
turned back on immediately after the short horn blast 
sounds or the engine will go back into RESET. See 
the lockout procedure in the Lockout Section. 


REMEDY 


When | try to run the engine, the diesel volume is OFF 
orvery low. 


The diesel volume has been programmed at a reduced 
volume or to be silent. Go to RESET Feature 6 and 
adjust the volume. See the section entitled “Using 
RESET to Program ProtoSounds” for more 
information. 





When | try to set the diesel volume, it resets itself to 
the original volume after | selected the new volume. 


You are trying to set the volume with a poorly charged 
or dead backup battery. See the section on Battery 
Backup for more information. 





When | try to set the Diesel Volume to O Volume, | still 
hear the cab chatter sounds. 


When the diesel volume is set to O, you will hear the 
Cab Chatter sounds because setting the diesel volume 
only controls the sound of the diesel engine itself. All 
other sounds, including Cab Chatter, the horn and bell 
will continue to play at the volume level set by the 
manual volume control knob located on the bottom of 
the chassis. See the section entitled “ProtoSound 
Volume Adjustment” for more information. 











The sounds seem distorted, especially when the 
whistle or bell is activated. 


28 


The overall ProtoSound volume has been set to high 
creating the distorted sounds. Try turning the volume 
control knob located on the bottom of the chassis 
counter clockwise to reduce the overall volume level. 


E8 Operating Manual 





BATTERY PROBLEMS REMEDY 


| get no sounds when the engine shifts between the 
direction states. 


The battery may be dead or needs charging. See the 
Battery Backup section for more information. 





After | turn off my transformer, my engine continues to 
make sounds before quitting with a ding of its bell. 


ProtoSounds continues to sound for approximately 10 
seconds after power to the track has been shut off. 





The sounds distort at low voltages. 


The battery is insufficiently charged or dead. Follow 
the recharging instructions found in the section entitled 
“Self Recharging Battery Backup System”. 





A repeating horn blast occurs after the power has 
been shut down. 


RESET PROBLEMS 





The battery is insufficiently charged or dead. Follow 
the recharging instructions found in the section entitled 
“Self Recharging Battery Backup System”. 


REME 


When | first turn the power on, the engine will not 
begin to run. | have to turn the throttle off and then on 
again to get the engine to operate. 


This is normal behavior. When power to the track is 
first turned on, ProtoSounds enters a “RESET” phase 
at which time the engine undergoes a system check. 
Power must be interrupted to get the engine into the 
Forward Phase. See the section entitled “DCRU 
Reverse Unit Operation” for more information. 





Whenever | interrupt the power from RESET to enter 
Forward, the engine goes back into RESET instead of 
Forward. | know this occurs because the bell dings 
twice. 


BRAKE SOUND PROBLEMS 





When the transformer is throttled down, the sounds 
won't play. 


Whenever ProtoSounds enters RESET after power 
has been off for more than 15 seconds, the 
microprocessor initiates a system check to determine 
that everything is in working order. This system check 
requires 2.2 seconds to complete during which time 
the engine will play the diesel startup sounds. We 
recommend that you don't interrupt the power in 
RESET until the diesel startup sounds have 
completed. This will guarantee that the system check 
will have been completed since the startup sounds 
take longer than 2.2 seconds to play. If the problem 
persists, we recommend that you operate the throttle 
with a slower movement as you interrupt the power in 
RESET and enter the Forward Phase 


REMEDY 


The brake features has not been activated. See the 
section on activating the brake feature for more 
information. The throttle voltage setting on the 
transformer is either not starting high enough or 
ending low enough to trigger the brakes sounds. Try 
increasing the throttle setting to 14 volts or higher 
before throttling down to 8 volts or less. 





The brake sounds continue to play even after the 
engine stops. 


The brake feature sound record lasts for three 
seconds. With practice you can control how quickly 
you should stop the engine to keep it in sequence with 
he sound of the brake’s squeaking. 





The brake feature was activated in neutral after the 
engine was running in forward, but the brake sounds 


would not play when triggered after the engine went 
back into forward or reverse. 





The brake feature will only remain enabled if it is 
riggered in the first direction state you enter after 
activating the feature in neutral. You cannot interrupt 
he power twice to enter another direction state and 
still have the brake feature active. Therefore, in order 
o make the brake sound feature operate in forward, 
you must first activate the feature in the neutral 

position that occurs after the engine was in the reverse 
state. 





After triggering the brake sound and stopping the 
engine in neutral, the engine begins making passenger 
station sound effects. 





After you trigger the brake sounds, you cannot stop 
he engine in neutral and leave the track power on 


without activating the passenger station sounds. If you 
don’t want to hear the passenger station sounds after 


entering neutral, turn the power off for three seconds 
o disable the passenger station sound effects. 





29 


E8 Operating Manual 





PFA PROBLEMS 


REMEDY 


The PFA feature does not begin even after stopping 
the engine and hearing the brake sounds. 


The power was not turned back on once the engine 
enter the neutral state thus disabling PFA.The 


transformer throttle was interrupted too quickly in 
neutral thus disabling PFA. Leave the throttle on in 
neutral until after the PFA arrival message plays. 





The PFA sound effects occasionally repeat 
themselves. 


ProtoSounds has a built-in random number generator 
that randomly selects each sound clip to play. 


Because there are only a total of 8 sound clips 
available in each PFA event, it is probable that a 
sound can occasionally be repeated one or more 
times. 





Once in PFA, the engine never goes in reverse. 


So that the passenger station sound effects and 
operation is as realistic as possible, ProtoSounds 
disables the reverse unit state whenever PFA is 
enabled. This way the engine never goes into reverse 
as the operator cycles through the various PFA 
events. 





When the engine enters PFA event 5, the bell 
automatically comes on. 


PFA has a built--in command to turn on the bell when 
the system enters Event 5. After approximately 15 
rings of the bell, it automatically will turn off. 





Whenever PFA is enabled, pressing the whistle and 
bell buttons has no affect. 


Because PFA must control various effects in each PFA 
event, the bell and whistle functions are disabled until 
either the PFA events have been completed, or the 
engine is shut down for 3 or more seconds. 





| can’t get PFA to begin when the engine is stopped in 
the neutral position. 





It is possible that PFA was never enabled or has been 
disabled. Try reactivating the feature by holding down 
the bell button for three or more seconds.

TRANSFORMER WIRING CHART 


ProtoSounds® is designed to work with any standard AC transformer that 
uses a “Pure Sine-Wave" format. The chart below lists the many Lionel® 
compatible transformers, such as the Lionel KW or ZW models. In 
addition, the chart details how the terminals on these compatible 
transformers should be attached to your layout. The Trainmaster system 
from Lionel® (marked with an asterisk below) will not function correctly 
with ProtoSounds without disrupting the sound effects. Therefore, 
whenever ProtoSounds senses that the Trainmaster system is being used, it 
automatically disables ProtoSound’s sound effects. The operator retains 
control over the engine, but no sound effects will play.

O-31 OPERATION 


While the MTH E-8 diesel is more than capable of operating on O-31 
curves and switches, you may find that certain light freight cars are prone to 
derailing when being pulled or pushed by the MTH E-8 through O-31 
switches. Should this occur, we suggest adding weight to the cars making 
them heavier and less likely to derail. 


WARNING: 


When using electrical products, basic safety precautions should be 
followed including the following: 


-- Read this and all related manuals (transformer/power supply, 
locomotive, etc.) thoroughly before using this device. 


-- This device is not recommended for children under eight years of age 
without adult supervision. 


-- MTH recommends parents examine the toy transformer used to power 
this device periodically for conditions that may result in the risk of fire, 
electric shock, or injury to persons, such as damage to the primary or output 
cord, plug blades, housing or other parts (including proper functioning of 
the circuit breaker), and that, in an event such conditions exist, the 
transformer should not be used until properly repaired.
