L = Initial length of segment = 79 m
T = Normal temperature = 
l = Width to be left for expansion
= Coefficient of linear expansion of the material = 
= Maximum temperature = 
= Change in temperature = 
The expression of linear expansion is given by
The expression for the minimum gap distance l the engineers must leave for a track rated at temperature is
