<p>A rail grinding vehicle, wherein a grinding disc (3) the rotational shaft (4) of which extends transversely to the longitudinal extension of the rail to grind a rail (1), and which vehicle is provided with measurement equipment (11-14) to measure on the one hand the distance of said grinding disc (3) to the rail before and after the grinding disc as also the essentially vertical variations of the rail, from the top to the bottom, before and after the grinding disc (3), the results from said measurement operations being supplied, together with the values representative of the measured rotational speed of the grinding disc and together with start or stop orders from at least one control panel (8), into at least one control unit (9), the latter continuously calculating the desirable distance to the rail and the rotational speed of the grinding disc (3) in response to said measurement results and emitting signals to the grinding-disc actuating means (6) and motor (5), so that owing to this measuring and control method the rail will only be ground wherever required and be ground to a sufficient but not excessive degree.</p> |
