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.

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.
Volume Control – To adjust the volume of all sounds made by this engine, turn the master volume control knob located under the engine clockwise to increase the volume and counter-clockwise to decrease the volume (see Fig. 1) . Volume Adjustment Knob Figure 1. Location of the Proto-Sound 2 Volume Adjustment Knob 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.
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.
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.
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.
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.
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.
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. Body Mount Screws Grease Gears (G) Body Mount Screws Motor Mount Screw Figure 3.
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.
One set of replacement tires is packaged with your model. Additional tires are available directly from the M.T.H. Parts Department (phone: 410-381-2580; fax: 410-423-0009; e-mail: parts@mth-railking.com; mail: 7020 Columbia Gateway Drive, Columbia MD 21046-1532). Locomotive Light Bulb Replacement To replace the light bulb in the locomotive, follow these instructions: Follow the cab removal instructions found in the “Lubrication and Greasing” section of this booklet.
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.
® 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; service@mth-railking.com, 7020 Columbia Gateway Drive, Columbia MD 21046-1532). Starting Up When I first turn the power on, the engine will not begin to run.
Cab Chatter Remedy Sometimes the Cab Chatter sounds don’t play. Cab Chatter plays only in neutral. Lock-out 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 is locked into the neutral position. Follow the procedure in the “Lock into a Direction” section. The engine won’t lock into forward, neutral, or reverse. Engine speed must be below 10 scale mph (approx. 10 volts or less in conventional mode).
PSA Remedy Once in PSA, the engine doesn’t go into reverse. 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.
Transformer Compatibility and Wiring Chart Note that many of the operational commands described in these instructions require a bell button, so if your transformer does not have its own bell button, you should consider adding one to get the full benefit of the system. Transformer Model Center Rail Outside Rail Min/Max.
Additional Features Accessible with the DCS Remote Control System: While conventional mode operation of a Proto-Sound 2.0 engine yields wonderfully realistic sound and several train control features, command mode operation allows the user to access a world of command functions never before accessible to O Gauge railroaders.
• Direction Control Set Up-User can set initial individual start-up direction (start in forward or reverse) for double-heading operations. • Locomotive Consist Set-up-User can determine locomotive values for consist make-ups, allowing multiple locomotives belonging to a consist to operate together. • Query Locomotive Information-User can query locomotive programming to learn locomotive address and engine data information, including scale miles traveled.
