Segmented brake pipe train control system and related method

摘要

A train control system is for a train comprising at least first and second train segments including a brake pipe being separated between adjacent train segments. The train control system preferably comprises a first control subsystem for installation in a locomotive of the first train segment and a second control subsystem for installation in a locomotive of the second train segment. The first and second control subsystems communicate with one another for controlling train braking. The system also preferably includes a third control subsystem for installation in a railcar adjacent an end of the first train segment. This third control subsystem preferably includes at least one pressure transducer for sensing brake pipe pressure adjacent the end of the first train segment, and at least one control valve for controlling brake pipe pressure adjacent the end of the first train segment. The third control subsystem also preferably includes a processor for communicating a signal related to brake pipe pressure adjacent the end of the first train segment to the second control subsystem, and for controlling brake pipe pressure adjacent the end of the first train segment responsive to a command from the second control subsystem. The second control subsystem and the third control subsystem preferably cooperate so that the brake pipe pressure adjacent the end of the first train segment and a brake pipe pressure adjacent a front of the second train segment are substantially matching thereby emulating operation with a continuous brake pipe.
