Graduated train braking
First Claim
1. A method for automatically controlling braking of a train being moved by a locomotive having a control system onboard for remotely controlling train operations comprising:
- applying a first degree of braking to a train during a first time period when the locomotive is being remotely controlled via an onboard control system in an absence of control inputs from an onboard operator, the first degree of braking based on a first deceleration force selected so that the train is slowed in a manner effective to limit a peak deceleration rate experienced by the train sufficient for reducing unintended movement of a rider onboard the train; and
applying a second degree of braking to the train during a second time period following the first time period.

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.
