Loram began grinding rails in the 1970s. High rates of speed, traffic, and weight can damage rails. The burrs and cracks created can damage train wheels, slow traffic, and cause rails to degrade faster. Grinding rails in place helps to avoid these problems and lengthen rail life. While Speno had its crews living on its grinding trains, Loram ...
Rail grinders will typically use a coarser stone to work out all of the dips and wear found along the rail head and a finer stone to finish the work and return the rail to a nice, polished finish. A crewman eyes the photographer as a Loram grinder rolls away at Hummelstown, Pennsylvania on March 13, 2007. Rob Kitchen photo.
