Mechanism and Calculation of Speed-Interval Control of High-Speed Passenger Trains

  • Received Date: 28 Feb 2005

  • The parameters,such as braking ratio,braking distance,operation time and so on,and a formula for calculating minimum headways were presented.The signaling and operations of high-speed passenger trains depend on the braking stage design and relative equipment configuration to fulfill a complete braking process.The speed-interval control of high-speed trains adopts the one-step braking curve mode,and multi-step braking curve is as a standby mode.The key to reduce the headway on a line is to cut down the headways of arrival trains at stations in the same direction.For passenger trains at a speed of 250 km/h and over,the headway of 3 min can be realized with the one-step braking curve mode plus deceleration in advance.In the mixed operations of passenger and freight trains,the headway of 5 min can be realized when the braking ratio is 0.8,and the effective length of arrival and departure track and the throat length are no longer than 1200 m and 800 m,respectively,for a freight train at a speed of 120 km/h;and the headway of 4 min can also be achieved when the braking ratio is 0.6 for a high-speed passenger train at a speed of 200 km/h.
