ABSTRACT:
A rail road rail grinding truck adapted to grind the top surface of the rail comprises at least one grinding unit of which the position is adjustable by means of a cylinder and also of rail-engaging bearing shoes following the undulations of the rail surface. Each unit comprises an adjustable stop member responsive to a servo-action regulation device as a function of the grinding wheel wear and also of the rail undulations, so that the point of contact between the wheel and the rail cannot fall below the grinding base determined by the bearing shoes.
