RailKing 2-8-0 Steam 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, 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.

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 maintain a constant
speed when speed control is turned off, you need to adjust track voltage
yourself.  When speed control is off, the volume will drop to allow for better
low voltage operation.  Full volume is restored upon reactivation of speed
control.

To turn speed control on and off,

 put the engine in neutral, then press the

transformer’s Whistle button one time then immediately press the Bell button
two times. Two whistle blasts will indicate that the engine has made the
change.  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.
