METHOD AND DEVICE FOR REPAIR AGENCIES HEIGHT POSITION AND ORIENTATION OF A RAILWAY TRACK.

摘要

The invention relates to a process and apparatus for correcting the surface of a railroad track by exerting pressure on the shoulders of the track from both sides thereof by means of vibrating compactors mounted on a vehicle chassis and provided with pressure applying jacks. The ballast is compacted beneath the track which raises it to a desired first track level which may be above the final desired track level, whereafter the track is tamped down to the desired level by means of a force applicator which imparts pulsating force to depress the raised track.
