[Solved] The track modulus is not affected by gauges.

Q.	The track modulus is not affected by gauges.
A.	true
B.	false
Answer» B. false
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/cm2, mg=42-54kg/cm2 and ng=30kg/cm2.
