RAILKING DOODLEBUG

DIESEL ENGINE

OPERATING

INSTRUCTIONS

Thank you for purchasing the RailKing Doodblebug Diesel Engine. This RailKing

Diesel Engine contains state-of-the-art electronics with many built-in automatic features

for incredibly realistic operation. Despite these advanced features, the locomotive is

easy to operate with any compatible standard AC transformer (see the compatibility

chart on page 17), and is completely compatible with most other 3-rail locomotives,

rolling stock, and accessories.

This locomotive is equipped with Proto-Sound 2.0 with Digital Command System

(DCS). This new system will allow you to operate your locomotive in Command mode

(when used with the DCS Remote Control System, sold separately) or Conventional

mode. Conventional operating features are described in the following pages, while the

DCS operating features are covered in the set of operating instructions that accompanies

the DCS equipment. Conventional Mode operation of this locomotive is much simpler

than operation of original Proto-Sound engines. For your own safety and that of your

equipment, please read the instructions before you operate this engine.

INITIAL LUBRICATION

Although the engine was lubricated at the factory, it is important that you

lubricate the chassis before operation. Lightly grease the outside idler and

drive gears (marked “G” in Fig. 3 on page 10) to prevent them from squeaking.

Use light household oil and follow the lubrication points marked “L” in Fig. 2

on page 9. Do not over-oil. Use only a drop or two on each pivot point.

At this point, you are ready to put your engine on the track and begin running

it.

BASIC OPERATION

Throttle – Throttle up the power to your track by either firmly pressing the

Direction button on your transformer or remote once or quickly dropping and

advancing the throttle to put the engine in forward.

Operation Buttons

Use the operation buttons on your transformer or remote as described below.

Horn/Whistle - To sound the horn, firmly press the Horn/Whistle button. The

horn will sound for as long as you continue to depress the button. It will stop

when you release the button.

Bell - To sound the bell, firmly press and release the Bell button. To turn the

bell off, press and release the Bell button again. The bell will continue to ring

from the time your turn it on until you press and release the button again to

turn it off.

Direction – Your train is programmed to start in neutral. To put the engine

into forward and then to change the direction of the train or to put it into

neutral, firmly press and release the Direction button on your transformer. Just

as you must stop your car between forward and reverse, this engine will not go

directly from forward to reverse; it goes into neutral between directions. If the

train has been moving forward, the first press of the Direction button will put

the train from forward into neutral, the second press into reverse, the third

press back into neutral, and the fourth back into forward. To prevent accidental

high-speed start-ups, this engine is programmed to restart in neutral each time

the track voltage is turned off for 10 seconds or more.

PROTO-SOUND

2.0 OPERATING INSTRUCTIONS

Because Proto-Sound 2.0 is an all-new system developed by M.T.H.’s own

research and development team, it operates differently from original

Proto-Sound. Most Proto-Sound 2.0 features are automatically enabled, and the

reset state has been eliminated, so there is no need to program features as with

original Proto-Sound. Although the new system is easier to operate than

original Proto-Sound, you should read these instructions thoroughly before

using Proto-Sound 2.0 features in order to prevent harm to yourself or your

equipment.

Activating Proto-Sound 2.0 Conventional Mode Features:

Proto-Sound 2.0 features are activated by sequences of Bell and Whistle button

pushes described below. Please read the full descriptions of each feature

before using it. To use these buttons to activate features rather than to blow the

whistle or ring the bell, you should press the buttons for a shorter time (½

second); you may need to practice your timing to make this work smoothly.

Feature to Be Activated:

Passenger Station Announcements (PSA):

Your engine is equipped with a sound package of Passenger Station

Announcements that you can play when you pull into a freight yard. Each

sequence described below will play as long as it is left on, randomly generating

sounds, but be sure to allow time between the button pushes described below

to allow the PSAs sufficient time to run through each sequence.

1. To cue the sound system to play the PSA, quickly but firmly press the Bell

button once followed by 2 quick presses of the Whistle button while the engine

is moving. As soon as you have keyed in this code, you will hear the

announcement for the upcoming stop and the bell will begin to ring.

2. Press the Direction button or drop and advance the throttle once to stop the

engine. This will trigger the first sequence of PSAs. The reverse unit is

temporarily disabled so that the train will not move as you use the Direction

button to trigger the sounds, and Proto-Sound 2.0 has disabled operator control

over the Whistle and Bell buttons until the full PSA sequence is complete.

3. After waiting at least five seconds for that sequence to run, press the

Direction button again to trigger the second sequence of PSAs.

4. After at least another five seconds, press the Direction button again to

trigger the third PSA sequence.

5. Again, after allowing about 5 seconds for the third sequence to run, press

the Direction button one more time to trigger the fourth and final PSA

sequence. You will know it is the final sequence when you hear the “All

Aboard!” call. The bell will begin to chime and within a few seconds, the

engine will start and move out on its own at the current throttle setting, in the

same direction it was traveling when you began the sequence. Once the bell

turns off, the operator regains control of the transformer’s bell and whistle

buttons and can ring the bell or blow the whistle as usual.

RailKing Doodlebug Electric Engine

Tips on Using PSAs

• You can terminate PSA at anytime by turning off power to the

track for 15 seconds.

• You do not have to be in Forward to use PSA. At the

conclusion of the full sequence, the train will pull away from the

station in whatever direction you were going when you activated

the feature.

• You can use PSA even if you are double-heading with another

engine regardless of whether the second engine is equipped with

a Proto-Sound 2.0 PSA module. If the second engine is not

equipped with PSA at all, you must remember not to leave the

throttle at a high voltage level once you have stopped the engine

to run the PSA. Otherwise, the engine without PSA will begin

vibrating on the track as its motors strain to move the train, since

they cannot be automatically disabled during the PSA cycle. If

the second engine (whether original Proto-Sound or Proto-Sound

2.0) is equipped with PSAs, you may choose to disable it when

used in double-heading operations, so you will not experience

competing PSA sounds. To disable PSAs in an original

Proto-Sound engine, see the operating instructions for that

engine.

Proto-Coupler® Operation

This locomotive is equipped with a coil-wound Proto-Coupler for remote

uncoupling action. Because the Proto-Coupler is controlled through the

Proto-Sound 2.0 microprocessor, it does not require an uncoupling track section

or modification to your layout to function. Use the codes listed below to fire

the coupler.

Rear Coupler:

To fire the rear coupler, quickly press the Bell button once followed

immediately by three pushes of the Whistle button. The sound of the liftbar

and air line depletion will play, and the knuckle will be released.

Front Coupler:

To fire the front coupler, quickly press the Bell button once followed

immediately by four pushes of the Whistle button. The sound of the liftbar and

air line depletion will play, and the knuckle will be released.

Speed Control:

M.T.H. engines equipped with Proto-Sound 2.0 have speed control capabilities

that allow the engine to maintain a constant speed up and down grades and

around curves, much like an automobile cruise control. You can add or drop

cars on the run, and the engine will maintain the speed you set.

While the engine is programmed to start with the speed control feature

activated, you can opt to turn it off. This means the engine’s speed will fall as

it labors up a hill and increase as it travels downward. It is also affected by the

addition or releasing of cars while on the run.

To turn speed control on and off, put the engine in neutral, then press the

transformer’s Whistle button one time then immediately press the Bell button

two times. Two horn blasts will indicate that the engine has made the change.

Repeat the 1 whistle, 2 bells code to return it to the other state. Youwillwant

to do this during the initial neutral upon start-up if you ever couple this

engine to another engine that is not equipped with speed control to avoid

damaging the motors in either engine. Each time you shut down the engine

completely, it will automatically turn speed control on.

RailKing Doodlebug Electric Engine

Lock into a Directional State:

You can lock your engine into a directional state (forward, neutral, or reverse)

to prevent it from changing directions. To do this, put the engine into the

direction you want or into neutral, to lock it into neutral, run it at a very slow

speed (< 10 scale mph), and quickly but firmly press your remote’s Whistle

button once followed immediately by three presses of the Bell button. Two

horn blasts will indicate that the engine has made the change. The engine will

not change direction (including going into neutral) until you repeat the 1

whistle, 3 bells code to return the engine to its normal state, even if the engine

is kept without power for extended periods of time.

Reset to Factory Defaults:

To override the settings you currently have assigned to the engine and reset it

to its factory defaults, quickly press the Whistle button once, followed

immediately by five quick pushes of the Bell button.

Automatic Sounds:

Certain Proto-Sound 2.0 sound effects automatically play in programmed

conventional mode conditions:

Squealing Brakesplay any time the engine’s speed decreases rapidly.

Cab Chatter plays when the engine idles in neutral.

Engine Start-up and Shut-down sounds play when the engine starts up and

shutsdown.

MAINTENANCE

Lubrication and Greasing Instructions

The engine should be well oiled and greased in order to run properly.

You should regularly lubricate the pickup rollers to prevent them from

squeaking. Use light household oil and follow the lubrication points marked

“L” in Fig. 2. Do not over oil. Use only a drop or two on each pivot point.

The locomotive’s internal gearing was greased at the factory and should not

need additional grease until after 50 hours of operation or one year, whichever

comes first. Follow the greasing instructions below. Note that in some tightly

packed engines you may need to move internal components temporarily in

order to access the gears.

1. Remove the screws from the chassis, as seen in Figure 3, then lift the body

away from the chassis.

2. Remove the black Phillips motor mount screw located on the bottom of the

truck block underneath where the pickup roller sits.

3. 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.

4. Reassemble the truck and motor, being careful not to pinch any wires

between the truck block and motor mount.

Lubricate Pick Up Rollers Lubricate Pick Up Rollers

Figure 2. Lubrication Points on the Locomotive

RailKing Doodlebug Electric Engine

5. Repeat the procedure for the other motor and truck

6. Reassemble the chassis and body, being careful that the wires are not caught

between the body and chassis, as this can lead to a short that may damage the

electronics beyond repair.

It is also a good idea to lubricate the outside truck block idler and drive gears

with grease occasionally. Add grease to the points marked with “G” in Figure

Cleaning the Wheels, Tires and Track

Periodically check the locomotive wheels and pickups for dirt and buildup,

which can cause poor electrical contact and traction as well as prematurely

wear out the neoprene traction tires. Wheels and tires can be cleaned using

denatured alcohol (not rubbing alcohol), which can be found in home

improvement stores, applied with a cotton swab.

Occasional cleaning of the track will also help to ensure good electrical contact

and to prolong the life of your engine’s tires. To clean the track, use a clean

rag and denatured alcohol (not rubbing alcohol). Unplug the transformer and

wipe the rails of the track, turning the rag frequently to ensure that you are

using clean cloth on the rails.
