This RailKing Diesel Engine contains M.T.H.’s Loco-Sound™ sound and train control system.

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 9) to prevent them from squeaking. Use light household oil and follow the lubrication points marked “L” in Fig. 2 on page 8. 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. Give enough power so that the engine’s headlight shines brightly. Then put the engine into motion by either firmly pressing the Direction button on your transformer or remote once or dropping and advancing the throttle to put the engine in forward. Operation Buttons Use the operation buttons on your transformer as described below. Horn/Whistle - To sound the horn, firmly press the Horn/Whistle button.
Speed Control: M.T.H. engines equipped with Loco-Sound 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.
Proto-Cast and Proto-Dispatch: When used with the RailKing Remote Lock-on (sold separately), ™ ™ Loco-Sound-equipped engines gain Proto-Cast and Proto-Dispatch features. Proto-Cast: This feature allows you to play audio recordings through your engine’s speakers. You must supply the audio source (a small portable is sufficient) and a male-to-male mini cable (1/8” plug, like that used for the headset with a portable CD/tape player) to connect your audio source to the remote lock-on.
Manual Volume Control – To adjust the volume of all sounds made by this engine, turn the master volume control knob located under the tender clockwise to increase the volume and counter-clockwise to decrease the volume (see Fig. 1). Loco-Sound Volume Adjustment Knob Figure 1.
Maintenance: Lubrication and Greasing Instructions The engine should be oiled and greased in order to run properly. You should regularly lubricate all outside idler gears and 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 Roller (L) Lubricate Axle Bushings (L) 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.

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.
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 reverse order.
Troubleshooting Loco-Sound™ Problems Although Loco-Sound 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 Starting Up When I first turn the power on, the engine will not begin to run.
Volume Remedy The sounds seem distorted, especially Loco-Sound volume is set too high. Turn the volume control knob on the when the whistle or bell is activated. bottom of the chassis counterclockwise to reduce the volume. 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 most standard AC transformers.
