A method for the improvement and drainage of a length of railway track employs a train to carry out the method whereby it is made possible to dismantle and reassemble the length of track together with its infrastructure. Ballast and earth are excavated from the track and replaced by a layer of sand which is distributed and compacted mechanically through an empty frame of a working truck of the train. Two travelling gantries are provided on the train and equipped both with a lifting device for a length of track and a lifting and tipping device for buckets. The working truck is also equipped with a strip for levelling a platform and a tamper. These two members are mounted on a common chassis supported by travelling on the two side parts of the empty frame of the working truck within the travelling supports for the gantries so that the levelling-tamping chassis may move freely by passing below the gantries.
A railway train for use in improving the drainage of a length of railway track, comprising a first set of rail cars for travelling on the length of track to be drained, which first rail cars are equipped for excavation and evacuation of the bed of the length of track, and a second set of rail cars for travelling on track adjacent to said length, which second rail cars are equipped for conveying materials for the new bed and the new rails of the length of track and which set comprises a working truck composed of two bogies joined by an empty frame having a length which is greater than the length of a section of rail, one of the bogies being for travelling on said adjacent track and the other bogie being for travelling on said length of track, which working truck is connected to the trucks of the second set of rail cars by tracks for gantries, and two travelling gantries being provided and equipped both with a lifting device for a length of rail and a device for lifting and tipping buckets, and the working truck being equipped with a strip for levelling the bed and a tamper, these two latter pieces of equipment covering the entire width of the bed and being supported by travelling on the two side parts of the empty frame.
