Abstract
A railroad track relaying train has, 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 have bogie trucks at both ends and are interconnected by means of coupling frames adapted to bear the adjacent ends of the working cars in the trackless working area and supported by caterpillar trucks adapted to keep the working cars on the selected path, when moving on the ballast cleared track bed. Each caterpillar truck is provided with hydraulic cylinders for raising and lowering the coupling frame relative to the respective truck and with mechanisms for driving and steering the truck.
