Sumitomo Metal Industries, Ltd. (Sumitomo Metals) and Sumitomo Corporation have received an order from Tokyo Metro Co. Ltd. for 240 bogies (120 rail cars). The bogies will equip the steering devices jointly developed by Sumitomo Metals and Tokyo Metro. This new steering bogie is designed to allow the axle to self-align with curvature, enabling the bogie to run steadily on curved track and decrease noise and wear on the wheels. Scheduled for operation from spring 2012, the bogies ordered will be used for the new 1000 Series cars of the Ginza Line of Tokyo Metro.
