On a railway track, two types of trains, passengers and freights, are being operated. The speed of freight trains is 22 km/h, the speed of passenger trains is not given. On this railway track; -transition curves are designed before and after circular curves, -the length of transition curves is equal to each other’s, -the actual cant is constant for all circular curves, -the radius of all circular curves is 2965 m. By passing from a circular curve, 0.93 m/sec2 lateral acceleration acts to freight trains in the centripetal direction. By passing from a mid-point of transition curve, 0 (zero) lateral acceleration act to passenger trains. Calculate the length of transition curve by using empirical formula and taking into account that the design speed is the speed of passenger trains.
