ABSTRACT:
An automated initial terminal testing system tests the air pressure and leakage of the brake pipes and the operation of brakes of railroad trains (10) in a terminal yard before trains are allowed to go on a railroad. The system includes end of train devices (16) attached to the trailing coupler of the last car of each train, head of train devices (14) connected to a source of yard air (26) and the air hose connection to the brake pipe of the first car of each train, and a central control console (18). The end of train devices, normally used to transit brake pipe pressure data to the engineer in locomotive when a train is on a railroad, monitors the air pressure in the brake pipe during the charging operation and transmits this data to the central control console. The head of train devices control the charging and venting of air pressure at the front of the train. These devices monitor air pressure and transmits this data to the central control console. In addition, the head of train devices respond to commands transmitted from the central console to perform the charging and venting operations. The central control console monitors the data sent by all end of train and head of train devices in the yard, sends commands to the head of the train devices, and provides either a pass of fail output for the trains under test.
