TRACKSIDE TEST PROGRAM FOR REGENERATIVE CHOPPER-CONTROLLED SUBWAY CARS

Six subway cars in Toronto were retro-fitted with a chopper control system which also provides regeneration capability during braking cycles. Testing was concurrent with a test program to evaluate vehicle performance. Trackside testing identified and investigated the level of chopper-produced interference in signals, communication, data transmission, remote supervisory control and traction power systems, Safety considerations, such as the possibility of sustained voltage on de- energized contact rail sections, were also investigated. Energy consumption of the chopper-equipped cars was expressed as a percentage saving compared with that of conventional cars.
