    The explanation is pretty accurate.With regard to expansion and contraction . This is known on the VR as ‘Creep” and there are paint marks on the side of the rail together with white posts fixed into the ground and the Gangers job is to measure the creep weekly, as indicated by the movement of the paint mark in relation the the creep posts.
    IAnother reason for the rough stone ballast is to cripple the Station Master when hi tries to uncouple during kick shunting. A great way to do an ankle. I know.
