ABSTRACT:
The invention is a method of and apparatus for continuously laying sleepers at permanent positions at predetermined intervals on a bed of ballast for a railway track, by means of a vehicle travelling along the track, which method comprises feeding each sleeper in turn from a stock of sleepers to a laying mechanism where the sleeper is held a little above the level of the bed of ballast, removing vertical support from beneath the sleeper at a position in advance of the intended permanent position of the sleeper so that the sleeper falls onto the bed of ballast in advance of its intended permanent position, drawing the sleeper along the bed of ballast until it reaches its intended permanent position and then completely releasing the sleeper in its intended permanent position. The invention permits the sleepers to be laid with greater accuracy than when using prior apparatus.
