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 lift bar 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. 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.
, 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.
