Research conclusions：Through analyzing the turnout technologies used for the high-speed railways at home and abroad, and combining with the applicable situation of speed-raising turnout in the past ten years and the successful experience of applying the simple turnout with movable-point frog of 60 kg/m rail steel in 200 km/h railways, this paper theoretically analyzes the current main speed-raising turnouts used in China and makes the proposals of making the optimum design of the speed-raising turnouts from the line type to the structures of the main components of the turnout to completely eliminate the potential hazards in safety of the current speed-raising turnouts, improve the overall technical level of the speed-raising turnout, better meet the needs of railway construction, development and operation.
