-1- Rail clip driving apparatus ABSTRACT OF THE DISCLOSURE There is disclosed a trolley which runs along unfastened rails of a track, in which each rail is positioned between a respective one of two pairs of housings on each sleeper, the trolley moving from sleeper to sleeper in order to complete permanent fastening of the rails to the sleepers. The trolley has a pair of rail-clip driving apparatus on each side, one associated with each rail, of which each comprise a pair of magazines for storing e-shaped clips, and a clip driver for each magazine which drives a lowermost clip in a stack of clips in the magazine into a sleeper housing. Each apparatus includes a longitudinally displaceable support tube on which the magazines are mounted , the tube moving one way or the other depending upon which magazine first comes into cooperation with its respective housing in order to bring the other magazine into cooperation with its housing. The apparatus may move laterally relative to the trolley via a pair of parallelogram linkages provided one at each end of the support tube in order to adjust the apparatus to a changing path of the rails. A sleeper lifter may be provided to raise sleepers which are too low, and a sleeper sensor responds to the presence of a metallic housing on a sleeper in order to stop the trolley as it advances from sleeper to sleeper.
