Q4; Calculate the maximum permissible speed on curve of high speed B.G. track having the following particulars: Degree of the curve =2°, Amount of superelevation = 8.0 cm, Length of transition curve = 150 m, Max. speed of the section likely to be sanctioned = 165 kmph. %3D %3D

Q1; What would be equilibrium cant on ( B.G.) curved track of 2%, If the speed of several trains running on it are : 20 trains at speed 50 kmph, 15 trains at speed 60 kmph, 10 trains at speed of 70 kmph & S trains at speed of 80 kmph. Also calculate the maximum permissible speed for this curve. Q2; If a 7° curve track diverges from a main curve of 4° in an opposite direction in the layout of a B.G. yard, calculate the superelevation and the speed on the main line, if the maximum speed permitted on the branch line is 35 kmph. Q3; If the wheel base of moving vehicle on a M.G. track is 4.88m, the diameter of wheel is 0.5m and depth of flanges below the top rail is 3.2 cm. Determine the extra width required to be provided on this curve, if the degree of the curve is 8. Q4; Calculate the maximum permissible speed on curve of high speed B.G. track having the following particulars: Degree of the curve =2°, Amount of superelevation = 8.0 cm, Length of transition curve = 150 m, Max. speed of the section likely to be sanctioned = 165 kmph. QS; Calculate the length of a transition curve for a B.G. curved track having 5° & a cant of 18 cm. the maximum permissible speed on curve is 105 kmph. Then find the offset of the transition curve for each 20 m.
