The surface re-shaper consists of two milling units equipped with height control cylinders (4,5,6,) and each comprising a frame (8,9), rollers (18) and a milling tool (24,24'), mounted beneath a railway vehicle (2). The two frames are articulated relative to one another about a pivot (20) with its axis perpendicular to the lengthwise axis of the rail, and they are of different lengths. The milling tools are mounted on supports (22,22') which can slide vertically relative to the frames, and connected to jacks (23) which control their positions relative to the rail. The re-shaper also has a rail heater situated in front of the milling tools, and a cooler behind them. A collector with a suction channel or magnet gathers the material removed from the rail surface during re-shaping. |
