Abstract

A railway freight brake system for operating vehicles in a train wherein each vehicle responds in braking situations to provide a generally uniform net braking ratio on all cars in the train. Embodiments include vehicles receiving a brake signal and utilizing either a received train net braking ratio or utilizing a stored on-board train net braking ratio to control pneumatic equipment on-board the vehicle to produce brake forces on the vehicle generally corresponding to the net braking ratio of the train. Some embodiments use a common train line control to communicate both train net braking ratio and brake signals to the individual vehicle. Individual vehicles can receive periodic or initial train net brake ratio values.
