1/4 mile rails are made by butt welding 76 foot lengths. They are then put on flat cars (with bunkers or poles to hold them from sliding off) the flat cars are coupled and the rails bend like wet sphagetti. When the total length is 1/4 mile long they start a new rail. This assembly is then shipped to where the new rail is required. It just bends around any corners that the train is going, just like the rails below which are carrying the train.
