TrainMaster Command Control operations

Tuning your locomotive's performance

T rainMaster Command Control allows you to fine-tune the performance of your locomotive.
Use your CAB-1 Remote Controller to make these adjustments.
Note! These settings will be lost if you assign a new ID#.
RPM LEVEL
Your locomotive's RPM level varies with the CAB-1 Remote Controller throttle in automatic
RPM mode. You may choose to set a constant, or fixed, RPM level in manual RPM mode.
Automatic RPM mode
The intensity of the RPM sounds will vary with adjustments to the throttle. When you stop
the locomotive for two seconds or more, the RPM sounds will return to their initial intensity.
This is the locomotive's default setting.
Manual RPM mode
Manual RPM mode allows you to set a constant RPM level for your locomotive. In this
setting, the RPM level will not vary with the throttle settings or the speed of the locomotive.
To set a constant RPM level, get your locomotive moving, then press AUX1, 3 or AUX1, 6
to enter manual RPM mode. The locomotive will be locked at the current RPM level. To adjust
the RPM level, press 3 to ramp up or 6 to ramp down. The locomotive will retain this setting.
When the locomotive is in motion, you may adjust the RPM level. To adjust the RPM level
after ten seconds have elapsed, simply press AUX1, 3 or AUX1, 6 again. To exit manual RPM
mode, turn off track power and allow the locomotive to reset, enter the shutdown sequence
(AUX1, 5), or reset the locomotive (AUX1, 0).
MOMENTUM
The TrainMaster Command Control momentum feature simulates the labored performance
of a locomotive pulling a light, moderate, or heavy load. Press L, M, or H (located under the
removable panel on the CAB-1 Remote Controller) to adjust the momentum setting. For quicker
response to your commands, press L, which is the factory default setting. Your locomotive will
keep this setting until it is changed.
ADJUSTING THE SPEED
The BRAKE and BOOST buttons give you incremental control of your locomotive's speed
while you press and hold these buttons, allowing you to make small, gradual adjustments
around curves and over grades. The locomotive will resume its initial speed when the buttons
are released. Listen for the squeal of your locomotive's brakes when you use the BRAKE button.
