10 RailKing 4-6-4 Steam Engine

Front Coupler:

To fire the front coupler (if your engine has one), quickly tap the Bell button once

followed by four quick taps of the Horn button, allowing approximately ½ second to

lapse between each quick button press. The sound of the liftbar and air line depletion

will play, and the knuckle will be released.

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. Because the engine will run more slowly at a given throttle voltage when speed

control is on than when it is off, you should adjust the throttle to a lower power level for

operation with speed control off to avoid high-speed derailments. When speed control is

off, the volume will drop to allow for better low voltage operation.

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

transformer's Horn button one time then quickly tap the Bell button two times, allowing

approximately ½ second to lapse between each quick button press. Two horn blasts will

indicate that the engine has made the change. Repeat the 1 horn, 2 bells code to return it

to the other condition. 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.
