RailKing GG-1 Electric Engine
Proto-Coupler® Operation
This locomotive is equipped with a coil-wound Proto-Coupler for remote
uncoupling action. Because the Proto-Coupler is controlled through the
Proto-Sound 2.0 microprocessor, it does not require an uncoupling track section
or modification to your layout to function. Use the codes listed below to fire
the coupler.
Rear Coupler:
To fire the rear coupler, quickly press the Bell button once followed
immediately by three pushes of the Whistle button. The sound of the liftbar
and air line depletion will play, and the knuckle will be released.
Front Coupler:
To fire the front coupler, quickly press the Bell button once followed
immediately by four pushes of the Whistle button. 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.
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
on.
