Setting Speed Control
1. Run the powered locomotive at the desired speed for approximately five seconds.
2. Press and hold the horn button.
3. While holding the horn button, increase the track voltage by at least three volts (at
least a quarter turn).
4. Release the horn button.
5. At this point, speed control is set.
The speed of the locomotive will increase slightly before returning to the set speed.
Turning Off Speed Control:
1. While the powered locomotive is in neutral, turn your controller up to the maximum
power (no more than 19 volts), wait one second, then press and hold the horn button.
2. While holding the horn button, slowly reduce track voltage to one-fourth of full power.
3. Release the horn button.
4. Cycle the locomotive to forward or reverse. The locomotive is now out of speed control
mode.
In conventional operation, the smoke unit and lights are connected directly to
track power. Do not exceed 14-16 volts for extended periods. Doing so will cause
damage to the locomotive.

The Odyssey System
T
he Odyssey System is a “cruise control”
for your engine. Once the speed is set
(see below), your engine will maintain a
constant speed, no matter what loads the
locomotive pulls or what grades you have on
your layout. This digitally-controlled system
also allows for extremely slow movement
that will amaze any “scale” enthusiast.
W
hile in the Command Control
environment, the speed control
feature of the Odyssey System is always on.
When turning the throttle, the speed of the
locomotive will respond to each signal from
the Command Base. For example, address
the locomotive and slowly turn the throttle.
The first flash of the red light on the
Command Base corresponds to the first
speed step. This is the slowest speed of the
locomotive.
