i. Range of temporary variation.

ii. The section of rail.

iii. Resistance offered by ballast to the longitudinal movement of rail assembly.

2. Formation - Weak formation to be identified and stabilized suitable means cross slope should be 1 in 40. In heavy rainfall areas steeper grades can be provided as prescribed by CE.
