TRAIN CHIEF® II LRCS w/Lightweight OCU OWNER’S MANUAL
95-00-0-xxx Rev 000 5-1 Control Chief Corporation
5 OPTIONS
The following optional features are included in your Train Chief® II system.
Special Features Supplied
Independent Brake Bail Option
The locomotive independent brakes are applied and released automatically by the locomotive
brake distribution valve (if equipped), in a manner similar to that which is achieved when braking
is controlled manually from the locomotive brake stand. The bail function allows the
independent brake to be released while the trainline brake continues to be applied.
Locomotive Mounted E-Stops
In addition to the E-Stop button located on the OCU, up to four (4) additional hardwired E-Stop
buttons can be provided on the locomotive. All E-Stop buttons are wired in series such that
activation of any one will command the E-Stop reaction. These additional E-Stop buttons must
be located on the locomotive, since they are hard wired into the receiver / controller unit.
Wheel-slip Alarm Option
When present, the existing locomotive’s wheel slip monitoring device can be monitored by the
locomotive remote control system. When wheel slip is detected by the LRCS the throttle can be
automatically reduced or maintained steady depending on customer’s decision at time of
purchase. Throttle advance is also restricted while there is wheel slip being detected.
Sanding Options
Direct electric control has been provided to initiate the locomotive sanding function. Typically
the dual function RESET / SAND
pushbutton as described in Chapter 3 is employed on the
OCU for this function. Sanding is always in the direction of travel.
