There are a lot of traffic jams in the metropolitan area and the commuting time has been longer nowadays. So the urban people has been interested in the GTX(Great Train Express) project in Korea. The GTX is the train which runs at 200km/h speed in underground tunnels. If the train also operates at high speed in tunnel section, the pressure wave will happen and the uplift force of pantograph may vary abruptly. If the rigid trolley bar system is used in tunnel section, it is difficult to improve the commercial speed of train. In order to improve the train speed in tunnel section, this paper presents the new pantograph concepts which can change the suspension stiffness and deals with the dynamic behavior characteristics of pantograph according to the parameter variation.
