Basic Operation
RailKing One-Gauge locomotives can be operated with AC or DC power output
transformers. When using DC output power supplies, the user can only control the
lcomotive speed and direction. The locomotive will still make engine sounds but no bell
or whistle control is possible when using a DC output power supply unless the user
wishes to hook up the power supply to MTH’s separately sold Digital Command System
(see below).
As with all G-Gauge locomotives, the Throttle knob or handle controls how fast your
train will travel.
Activating Features Using DC Power
Throttle -
To increase or decrease track voltage, and therefore train speed, turn or slide
the throttle control knob. Turning clockwise will increase voltage and speed, while
turning counterclockwise will decrease voltage and speed. Because your RailKing One-
Gauge locomotive is equipped with M.T.H.’s Proto-Speed Control feature, the engine will
maintain the speed you set after you release the throttle until you turn it again to slow
down or speed up the locomotive. This feature works very similarly to the cruise control
system found in automobiles and allows the engine to maintain its speed even as it enters
curves, traverses grades or coasts down inclines.
Direction
- There are two ways to change a locomotive’s direction when operating the
engine with a DC power supply.
1. Slow the locomotive down using the throttle knob until the engine comes to a
complete stop but power still remains on the track. Slide the direction switch on the
power supply to the opposite direction and increase the throttle setting again to allow the
locomotive to begin running in the opposite direction.
2. While the locomotive is running, slide the direction switch on the power supply to the
opposite direction. The locomotive will slow to a gradual stop and then reverse direction
and slowly gain speed until it is again travelling at its original speed prior to the direction
switch change.
