PCT No. PCT/EP90/00819 Sec. 371 Date Apr. 29, 1991 Sec. 102(e) Date Apr. 29, 1991 PCT Filed May 8, 1990 PCT Pub. No. WO90/14470 PCT Pub. Date Nov. 29, 1990.A process for the continuous welding of railroad rail sections (3) during the laying down thereof, involves a particularly equipped train set (5-5'), formed by one or more trucks (5,5') having a lowered load platform inserted into the operating train, between the trucks (1) which carry the new rail sections (3) and ties (2), and the operating machine which lays them down. On board this equipped train set (5-5') there are performed the operations for arranging to line, to level and to abut the subsequent rail sections (3), as well as their welding, by welding machines (15-17) which are movable on a trolley (8) along the train set (5-5'). The welding operation is performed during a stroke of the trolley (8) with the welding machines (15-17) in a direction opposite the forward direction of the operating train, and the welding stroke is subsequently compensated by a return stroke of the trolley (8) with the welding machines (15-17 ) in the same direction as the forward direction of the operating train, whereby the whole welding operation is accomplished on board the operating train itself, and the laying down of new rails is done by the correspondingly operating machine on already continuous rails. |
