Car Repair Billing (CRB) is the system through which car shops and running repair agents get reimbursed for repairs they make to freight cars.
The Locomotive Speed Limiter (LSL) is a system for controlling brake applications on locomotives operating under Automatic Train Control (ATC). By controlling brake application rate, LSL reduces the risk of derailments due to high buff forces caused by aggressive penalty braking, while still permitting the train to stop within a safe distance. LSL is required on Amtrak-owned trackage, such as in the Northeast Corridor.
LSL-equipped locomotives are equipped with an amber light to signal that LSL is active.
Flat spots or depressions in the rail caused by excessive wheel slip.
Movement of freight between terminals, generally over long distances. Excludes pickup/delivery or switching.
