Abstract

The train is fitted with electro-pneumatic brakes operated by brake and venting control lines and monitored by feedback signal lines for each function. A transmitter/receiver is coupled to the lines in the engine and provides a test frequency down the lines. The end of the train has the four lines terminated by three identical value capacitors. The signal modulation gives an accurate, immediate safety check to see if any line is open circuited or short circuited, without requiring a test line to be fitted along the train. The system operates independently of the length of the train.
