The Concept of Rail Grinding was originated in 1930s for removal of rail surface defects. First production grinder was built in 1954 by Frank Speno Railroad Ballast Cleaning Co. It was a 9 car train with 96 grinding motors (7.5 hp each) working at 3 kmph. Later Speno International and Loram Maintenance of Way built many different types of

This angle grinder guide rail is strong and fit for both lateral and radial loads. They include dovetail slides, cylindrical column slides, and Boxway slides. On the other hand, bearing slides rely on a roller element that minimizes friction. They are ideal for light-duty uses as the bearing tends to break or deform when high pressure is applied.

Recent rail accidents have highlighted mobile phone use as a source of distraction in rail safety work. On 12 September 2008, in Chatsworth, California, a passenger train collided head-on with a freight train. The passenger train locomotive and lead passenger car derailed and the freight train's two locomotives and 10 of 17 cars also derailed ...
