ABSTRACT:
A track renewal train includes a vehicle bridging an intermediate right of way section between an old and a new track section, and this vehicle carries rail spreaders as well as equipment arranged in succession for removing the ties of the old track section, for lowering the level of, and planing, the ballast in the intermediate right of way section and for laying the ties of the new track section. The ballast lowering and placing equipment includes a ballast planing shield mounted on the vehicle and having a width at least equal to the length of the ties of the new track section, a ballast conveyor elevator associated with the ballast planing shield, the elevator extending over the width of the shield and having an input end adjacent the front end of the shield and an output end at the trailing end of the shield, and a ballast dumping conveyor arranged to receive ballast from the output end of the elevator. The ballast dumping conveyor bridges over the spread rails guided in the longitudinal direction of the train and has ballast outlets laterally outwards of the spread rails or in the cribs of the new track section.
