Abstract

1433045 Relaying railway track FRANZ PLASSER BAHNBAUMASCHINEN INDUSTRIE GmbH 25 April 1973 [2 May 1972] 19642/73 Heading E1G In a continuously advancing railway track relaying train of the kind in which the forward vehicles run on the old rails 3, the rear vehicles run on the new rails 3' (or possibly on the relaid old rails), and in which the lifted rails are held raised and spread apart over an intermediate trackless zone by guides such as rollers 8, the guides 8 are mounted on a bridging beam 2 whose opposite ends are pivoted to wheel pairs or bogies 4, 4' running on the old and new rails respectively, the beam 2 carrying apparatus such as rail lifters 7, 7', means 9-11-12 for lifting turning and conveying the old and new sleepers, and possibly a ballast plough. The train is suitable for conditions where the ballast has been prepared-e.g. cleaned and levelled-in a preceding operation leaving the sleepers resting on the ballast with the infill ballast for the sleeper spaces stored beyond the sleeper ends. The wheeled beam 2 may be capable of self-propulsion. To facilitate accurate positioning on curves the sleeper-handling tools 9 and/or the whole beam 2 may be transversely adjustable. In the sleeper handling operation described a pair of old sleepers 6 are lifted, turned through 90‹ to lie parallel to the track, raised above respective longitudinal conveyers 11 which are then transversely shifted to receive them, lowered on to the conveyers 11 and thence transferred to laterally-swingable longitudinal conveyers 12. The new sleepers 6' are laid by similar apparatus and are accurately positioned on the top of the prepared ballast.
