Abstract
A method for the improvement and drainage of a railway track employs a train comprising a working frame-car to carry out the method whereby it is made possible to dismantle and reassemble the track together with its infrastructure. The old track spans are removed, ballast and earth are excavated from the track and replaced by a layer of sand and by new ballast which are distributed, levelled and compacted mechanically. All these operations are taking place in succession through and within the empty frame of said frame-car as the latter is stationary bridging the working site. Two travelling gantries are provided on the train and equipped both with a lifting device for a track span and a lifting and tipping device for buckets. The working car is also equipped with means for excavating, digging, levelling and compacting.
