Abstract
A system (10) and method for automatically controlling braking of a train (38). The method includes applying a first degree of braking to the train during a first period of time, and then applying a second degree of braking to the train during a second time period following the first time period so that the train is slowed in a manner effective to limit a peak deceleration rate experienced by the train. The system includes a sensor (36) providing a signal indicative of an operating condition of a locomotive of the train requiring braking of the train, a memory (22) storing a braking schedule, and a processor (18) comprising logic executable for accessing the braking schedule stored in the memory responsive to the signal to automatically control braking of the locomotive according to the schedule.
