Premier P-47 Pacific Steam Locomotive
12
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.

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.
