Sizes under 100 lb/yd (49.6 kg/m) rail are usually for lighter duty freight, low use trackage, or light rail. A major difficulty with manufacturing rails is the newly-rolled hot rail warping as it cools, due to differential contraction between the head and foot. It took many decades to improve the quality of the materials, including the change from iron to steel. The supposed advantage was that, when the head became worn, the rail could be turned over and re-used. 1 YARD BRASS RAIL - AG228. Provides both mechanical and electrical bonding. SAT - CLOSED.
