INDUCTIVELY-COUPLED CONNECTORS FOR SIGNALLING AND BRAKE CONTROL ON LONG FREIGHT TRAINS
Sixty tuned, inductively-coupled, connector pairs (120 units) have been prepared for field testing. A set of these connectors has been subjected to a series of electrical and mechanical tests. Some additional units have been tested to destruction in heating and impact tests. The connectors have an efficiency of 92 per cent, a power handling capability of 100 watts, a passband of 15 kHz, and an operating-temperature range of minus 94 degrees F to 200 degrees F. A demonstration transmission line carrying three communications and signalling channels was set up with 54 connector pairs in series. Ways of increasing the connector efficiency have been investigated, and a proposal for a device combining the air-pressure and electric lines has been presented. The principal recommendation coming out of this work is that the device should be field tested on a unit train.
