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.

RailKing Doodlebug Electric 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:

RailKing Doodlebug Electric Engine
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.
5
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.

RailKing Doodlebug Electric 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. You will want 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.
7
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 shuts down.

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.
Lubricate Pick Up Rollers Lubricate Pick Up Rollers
Figure 2. Lubrication Points on the Locomotive
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.
9
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
3.

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.

RailKing Doodlebug Electric Engine
Traction Tire Replacement Instructions
Your locomotive is equipped with two neoprene rubber traction tires on each powered truck block. While these tires are extremely durable, you may need to replace them at some point.
Turn your engine upside down. If there are visible Phillips screw heads between the truck frame and truck block (see Fig. 4), go to step A. If not, go to step B.
A. Remove the two
Phillips screws that attach the truck sides to the truck block.
Truck Screws
B. Remove the trucks from the chassis and the truck sides from the trucks in order to slip the new tire over the grooved drive wheel. See Fig. 3 for which screws you must remove to do this.
Figure 4. Area to Look for Screws
Then:
1. Make sure the old tire has been completely removed from the groove in the drive wheel, using a razor blade or small flathead screwdriver to pry away any remains.
2. Slip the new tire onto the wheel. You may find it useful to use two small flathead screwdrivers to stretch the tire over the wheel.
3. If you twist the tire while stretching it over the wheel, you will need to remove and reinstall the tire. Otherwise your engine will wobble while operating.
4. Make sure the tire is fully seated inside the groove. Use a razor blade to trim away any excess tire that doesn’t seat itself inside the groove properly.
5. Reassemble in the reverse order.

RailKing Doodlebug Electric Engine
Self-Charging Battery Back-Up
The special NiCad 7-cell 8.4v self-charging battery in this engine improves performance at any speed. It ensures that power to the sound system will remain on during directional changes, or when traveling over dirty track or switches. The self-charging battery system is automatically turned on or off whenever track power is turned on or off.
Track power (when applied) recharges the battery, which should last for up to five years, and the special NiCad battery is a dry battery that should not leak or cause any damage to your engine. However, even this special battery will eventually wear down and need to be replaced. When you notice that your engine sounds seem distorted or garbled at low voltages or become silent when power from the transformer is turned off, test the battery to determine whether it should be recharged or replaced.
• Put the engine in neutral and leave the track voltage at 12 volts for 15 minutes.
• If the garbled or distorted sounds are reduced, the battery charge has run down and can be recharged. Do this by leaving the engine in neutral with track voltage at 12 volts for 6-7 hours so the battery can fully recharge (if your engine has a smoke unit, be sure it is turned off). Or you can remove the battery (see Fig. 6 below) and charge it in any standard slow charge battery recharger, following the recharger’s directions.
• If the sounds are not improved at the end of the 15 minute test charge, it is time to replace the battery (see Fig. 6 below). Contact the M.T.H. Parts
Department (phone: 410-381-2580; e-mail: [email protected]; mail:
7020 Columbia Gateway Drive, Columbia MD 21046-1532) for a replacement battery. A standard 9v alkaline battery can be substituted until your replacement arrives, but since alkaline batteries cannot be recharged, it will eventually wear down. Do NOT use a 6-cell 7.2v battery like those found in most convenience stores.

Troubleshooting Proto-Sound
®
2.0 Problems
Although Proto-Sound 2.0 has been designed and engineered for ease of use, you may have some questions during initial operation. The following table should answer most questions. If your problem cannot be resolved with this table, contact M.T.H. for assistance (telephone: 410-381-2580; fax:
410-423-0009; [email protected], 7020 Columbia Gateway Drive,
Columbia MD 21046-1532).
Starting Up R emedy
When I first turn the power on, the engine will not begin to run. I have to turn the throttle off and then on again to get the engine to operate.
This is normal behavior. To prevent accidental high-speed start-ups, Proto-
Sound 2.0 is programmed to start up in neutral anytime track power has been turned off for several seconds.
See the "Basic Operation" section for more details.
Horn
When I press the whistle button, the bell comes on instead.
R emedy
Reverse the transformer leads.
I can’t get the horn to blow when I press the whistle button.
quickly. Try pressing the whistle button more slowly, taking approximately one full second to fully depress the button.
Bell
When I press the whistle button, the bell sounds.
R emedy
Reverse the transformer leads.
I can’t get the bell to ring when I press the bell button.
You may be pressing the button too quickly. Try pressing the bell button more slowly, taking approximately one full second to fully depress the button.
The bell won’t work on a separate bell button.
Check the wiring of the separate button.
Coupler
When I try to fire the coupler, FYS starts.
R emedy
You are waiting too long between whistle button presses.
The Proto-Coupler won’t let the engine uncouple on the fly.
Try lubricating the coupler knuckle with a dry graphite lubricant. Do NOT use oil.
The coupler does not fire or stay coupled.
The coupler needs to be cleaned.
Wipe with denatured alcohol (not rubbing alcohol) and let dry.
14
RailKing Doodlebug Electric Engine
Cab Chatter
Sometimes the Cab Chatter sounds don’t play.
Lock-out
Remedy
Cab Chatter plays only in neutral.
Remedy
I can’t get the engine to run after I power up the transformer. It sits still with the engine sounds running.
The engine won’t lock into forward, neutral, or reverse.
The engine is locked into the neutral position. Follow the procedure in the
“Lock into a Direction” section.
Engine speed must be below 10 scale mph (approx. 10 volts or less in conventional mode).
Remedy Volume
The sounds seem distorted, especially when the whistle or bell is activated.
Proto-Sound 2.0 volume is set too high. Turn the volume control knob on the bottom of the chassis counterclockwise to reduce the volume.
Battery Remedy
The engine will not leave the initial neutral setting
Check to be sure the battery is installed and fully charged. See the
“Self-Charging Battery Back-Up” section.
I get no sounds when the engine shifts between directions.
The battery may be dead or need to be charged. See the “Self-Charging
Battery Back-Up” section.
After I turn off my transformer, my engine continues to make sounds before quitting.
Proto-Sound 2.0 is designed to continue to sound for a few seconds after power to the track has been shut off.
PSA
The PSA sounds occasionally repeat themselves.
Remedy
Proto-Sound 2.0 has a built-in random number generator that randomly selects each sound clip to play.
Because there are a limited number of sound clips available in each PSA sequence, it is probable that some of these sound clips will be repeated from time to time.
15
RailKing Doodlebug Electric Engine
PSA
Once in PSA, the engine doesn’t go into reverse.
Remedy
So that PSA effects can be as realistic as possible, Proto-Sound 2.0 disables the reversing unit whenever PSA is enabled. This way the engine remains still at its stop as the operator cycles through the PSA sequences.
When the PSA enters its last sequence the bell automatically comes on.
PSA is programmed to start ringing the bell at that point. After approximately 12 rings of the bell, it will automatically turn off.
When PSA is enabled, pressing the whistle and bell buttons has no effect.
Because PSA must control various effects in each sequence, Proto-
Sound 2.0 takes control of these sound effects until you exit PSA.
I push the direction button but the next sound clip in the sequence does not
Each PSA clip must play for approx.
30 seconds before PSA will advance play or the engine does not come out of PSA after fourth press of the direction button.
to the next step in the PSA cycle. Wait at least 30 seconds in each PSA sound clip before pressing the direction button.
Compatibility
This engine will operate on any traditional O-31 or larger O Gauge track system, including M.T.H.’s RealTrax® or ScaleTrax™ or traditional tubular track. It is also compatible with virtually most standard AC transformers.
(See page 17 for a complete list of compatible transformers and wiring instructions.)
