Best 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.
