Proto-Coupler Operation
This locomotive is equipped with one or more coil-wound Proto-Couplers for
remote uncoupling action. Because Proto-Couplers are controlled through the
Proto-Sound 2.0 microprocessor, they do not require an uncoupling track section
or modification to your layout to function. You can fire a coupler from neutral or
while in motion. Use the code shown below to fire the coupler(s).
Rear Coupler:
To fire the rear coupler, quickly tap the Bell button once followed by three quick
taps of the Horn/Whistle 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.

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/Whistle 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.
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.
