4.6 Speed-Time Curve for a Traction System: Scheduled and Average Speed and Factors Affecting these Speeds
A train runs between two stations 2 KM apart at an average speed of 40 km/h. The run is to be made according to simplified quadrilateral speed time curve. If the maximum speed is to be limited to 60 km/hr, acceleration to 2 km/hr/sec, Coasting retardation to 0.15 km/hr/sec and braking retardation to 3 km/hr/sec. Determine the duration of acceleration, coasting and braking periods.
