The track modulus is not affected by gauges.(a) True(b) FalseI have been asked this question in homework.My question is from Railway Engineering topic in portion Other Major Topics in Civil Engineering of Basic Civil Engineering

Answer»

Right answer is (b) False

The best explanation: As the THREE gauges (narrow-NG, metre –MG and broad-BG) increases, the components of the permanent part (like BALLAST and SLEEPER) also increases in size. As a result track MODULUS also increases. The recommended track modulus is: BG = 70 to 90kg/cm^2, MG=42-54kg/cm^2 and NG=30kg/cm^2.
