A radio-frequency (RF) deicing system for third rails has been proposed. It consists of an RF generator, transmission lines, a work coil, and a mechanical scraper, all mounted on a train. The system definition of such a setup is presented. Several coil configurations are studied. Experimental setups for static calorimeter tests, dynamic temperature rise tests, and deicing tests are described, and results are reported. With 50-kW 185-kHz RF generator power, successful deicing was accomplished up to a speed of 43.5 km/hr at an ambient temperature of -2.2ousC using a ferrite-core coil. Finally, possible future improvements to the system are discussed.
