Abstract
A rail head re-form grinding machine is provided with an annular grinding wheel whose lower flat face is adapted to engage and grind the rail head. A circular feeler device fits within the annular grinding wheel and is also engaged by the rail head. The feeler device is vertically movable by a hydraulic piston arrangement the movement of the feeler device being sensed and indicated by a sensing and indicating assembly. The housing which mounts the grinding wheel and feeler device is pivotally carried so that an arcuate surface may be ground on the rail head.
