Development of the New Concept Steering Bogie

Abstract

As for railway vehicle, there are many problems in sharp curve negotiation such as large lateral force, squeal noises and excessive wear of wheel flange and rail gauge corner. To solve these problems, single axle steering bogie has been developed by Tokyo Metro and Nippon Steel & Sumitomo Metal Corporation, and Tokyo Metro adopted this newly developed steer- ing bogie for the new train series 1000 for Ginza-line. The series 1000 has started commer- cial operation in April 2012 and silence of cabin is highly appreciated. In this paper, the design concept and outline of steering bogie for series 1000 are described. And curving per- formance of steering bogie for series 1000 is evaluated based on the result of field test.
