Railways

1.Mr. W. Simms, the consulting Engineer to the Government of India recommended the gauge for Indian railways

1.435 m as adopted in England 1.800 m as per Indian conditions 1.676 m as a compromise gauge 1.000 m as a standard gauge

2.If absolute levels of rails at the consecutive axles A, B, and C separated by 1.8 metres are 100.505 m, 100.530 m, and 100.525 m respectively, the unevenness of rails, is

0.065 m 0.055 m 0.045 m 0.035 m

3.A CST-9 sleeper consists of

two inverted triangular pots on either side of rail seat a central plate with a projected key and box on the top of plate a single two way key provided on the gauge side to hold the rail to sleeper all the above

4.Charles Vignoles invented the flat footed rails in

1814 1836 1846 1873

5.To design a cross-over between parallel tracks, the required components are :

two switch, points, two acute angle crossings and two check rails two switch points, two acute angle crossings and four check rails two switch points, two acute angle crossings and six check rails none of these.
