Shinkansen signalling system uses track circuits to detect Shinkansen trains. The basic logic of train signalling is that one train should not be introduced to the section where another train exists. So that the train detection information is very important and treated as absolute information. Track circuit uses rail as a part of electrical transmission line, and detects train by the short circuit which is composed by train axle and the both side rails, so it is very stable and reliable. Furthermore track circuit is used to transmit speed signal information to the train cab via the induction coil on the train. Shinkansen is 25000V A. C. electrified line that there are many harmonic waves in the power supply circuit and obstruct the track circuit current. To avoid this obstruction, Shinkansen track circuit adopts synchronized SSB, Single Side Band, system. This system is very excellent system without a fatal accident during 33 years since Shinkansen had begun its operation in 1964. Nevertheless the electromagnetic environment has been changing with the introduction of the high power rolling stocks with the standstill system like PWM, Pulse Width Modulation, converter, inverter, and so on. As the result of it, non-synchronized noise has increased. Moreover there are several problems in the synchronized SSB system now, for example, information number shortage and so on. So that new type signalling systems are being proposed. To evaluate new system, electromagnetic noise endurance character is necessary. In this paper, precise analysis of the Shinkansen track circuit electromagnetic environment is discussed, and electromagnetic noise endurance character of new type systems are evaluated. Moreover the character research of each system is carried out.
