GE Transportation describes SSC as a new-generation system that "continuously monitors the actual speed of train, thereby guaranteeing that its maximum speed is not violated." When necessary, the system can enforce braking. SSC has already been adopted on more than 5,000 kilometers (3,100 miles) of lines managed by RFI, the Italian Railway infrastructure group.
Erie, Pa.-based GE Transportation is a subsidiary of Fairfield, Conn.-based General Electric Co.
