ABSTRACT:
A railroad track relaying train comprises, in addition to the cars for transporting the ballast screening machines and a car equipped with power-wrenches for fixing the tie-screws, a sequence of working cars including a tie- and rail-removing car, a ballast clearing car, and a tie and rail laying car, these cars being interconnected by means of coupling frames supported by caterpillar trucks adapted to keep the working cars on the selected path. The tie and rail removing car comprises an elevator capable of lifting and rotating at least one tie or a track span around ballast conveyors, in order to deposit at least one tie or track span upon a transport element. The train is capable of performing all of the operations necessary for removing the old track, excavating and screening the old ballast, and laying the new track on the screened ballast, without stopping its forward motion when removing the old track.
