M.T.H. engines equipped with Proto-Sound 3.0 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.

Locking Locomotive Into A Direction
You can lock your engine into a direction (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 tap the Horn button once followed by three
quick taps of the Bell button, allowing approximately ½ second to lapse between each
quick button press. 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 condition, even if the engine is
kept without power for extended periods of time.
