(54) Rail grinding apparatus and method


(57) A rail grinding apparatus has a first power driven grinding section (20) and a second section (22) which rolls along the rail. Rotation of the wheel(s) of the second section (22) is caused by driving the apparatus along the rail, and the energy from this rotation at least partially drives the first section (20). The second section can also carry out a non-powered grinding operation as well as providing power for the first section.
