Abstract:
1. A rail profiling device for a railway crossover on which travels a rail vehicle having wheels with a frusto-conical profile having a profile angle conically diverging, the frusto-conical wheels substantially having an off-center point of contact with rails of the railway, the rail profiling device for planing a raised weld area on the railway crossover and comprising: a frame having a first rail-side member and a second rail-side member laterally spaced from each other; a plurality of wheels connected to the frame, the plurality of wheels being arranged on opposite rail-side members and spaced a distance between each other such that the wheels are configured to be mounted on laterally spaced rails of the railway, such that the distance between wheels of opposite rail-side members is equivalent to an axle width of the rail vehicle of the railway, the frame wheels having a frusto-conical wheel profile conically diverging at substantially the profile angle, and a planing device positioned on the first rail-side member to plane the raised weld area on the crossover to provide a crossover wheel contact surface profile along the entire length of one side of the railway crossover, the wheel contact surface profile being planed according to the profile angle of the rail vehicle wheels, wherein the frame wheels substantially have the same off-center point of contact with the rails of the railway as the point of contact of the wheels of the rail vehicle.
