ABSTRACT:
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.
