Front Coupler:
To turn speed control on and off
To fire the front coupler (if your engine has one), quickly tap the Bell button once
followed by four quick taps of the Horn 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.
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.
, 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.

If you experience poor or no smoke output when the smoke unit is on and has
fluid, check the wick to see if it has become hard, blackened, and unabsorbent
around theheating element. To remove the smoke unit you will first have to
remove the boiler shell (by removing the body mounting screws shown in Fig. 6
on pg. 13). To do this, follow these instructions:
1. Once the boiler has been removed, locate the smoke unit assemby (see Figure 14).
2. Use a phillips head screwdriver to remove the inspection cover screws as seen in
Figure 15.
3. After removing the inspection cover, inspect the wick. If it is darkly discolored
and hard, it should be replaced.
Replacement parts and wick replacement instructions are available directly from
the M.T.H. Parts Department phone: (order online: www.mth-railking.com, e-mail:
