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.
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 MTH’s Speed Control feature, the engine will
maintain the speed you set after you release the throttle until you turn it again to change
the voltage and speed. This feature works very similarly to a 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 - To change locomotive direction, slow the engine 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.
Activating Features Using DC Power
Using DCS With DC Power
MTH’s revolutionary Digital Command System, or
DCS, allows users to control their RailKing
One-Gauge locomotives in a command control
evironment. User’s can remotely access hundreds
of features inside each RailKing One-Gauge
locomotive with the wireless remote control.
Digital signalling and an easy-to-use interface make
using DCS a snap. More information on DCS can
be found on page 26 or by visiting
