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. It is also affected by the
addition or releasing of cars while on the run. The engine will run more slowly
at a given throttle voltage when speed control is on than when it is off.
To turn speed control on and off,
put the engine in neutral, then press the
transformer’s Whistle button firmly but quickly one time then immediately
press the Bell button two times. 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
o n .
Direction Lock:
You can lock your engine into a directional state (forward, neutral, or reverse)
so that it will not change 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
crawl (as slowly as it will move without halting), and quickly but firmly press
your remote’s Horn 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 horn, 3 bells code to return the engine to its normal state, even if
the engine is kept without power for extended periods of time.
