Abstract
A low noise current collector 20 having excellent controllability and response, and a high speed railway train using such current collectors. The current collector 20 includes an aerodynamically shaped current collector head 22, a driving cylinder 32 to move the current collecting head, a supporting insulator 30, and a cable head 50 supporting a conductor 53 for conducting current from current collecting head 22 to a load. The current collector 20 is controlled by a cylinder 7 for raising and lowering so that the current collector may be contained in a dome 4 when it is in use. A multi-car train has four current collectors, two toward each end, and each current collector has its front side directed toward the center of the train. The two current collectors at the rear of the train are utilized, while the two at the front are contained within their domes 4. Therefore, the train can run in either direction, utilizing the appropriate pair of current collectors.
