ABSTRACT:
A method of working a main track and a laterally adjacent track in a track switch section in tandem comprises the steps of intermittently moving a track leveling, lining and tamping machine with lifting tools and vertically and laterally adjustable, vibratory tamping tools along a main track, lifting the main track under the control of a reference system with the lifting tools to a desired level at respective longer ties connecting the tracks, and tamping ballast under the lifted ties with the tamping tools. A switch leveling and tamping machine with lifting tools is moved along the laterally adjacent track and, in the same operating stage, at least one of the rails of the laterally adjacent track is lifted with the lifting tools of the switch leveling and tamping machine, and ballast is tamped under at least a portion of the longer ties at the laterally adjacent track. The ballast tamping is completed under any not previously tamped ties or portions of the longer ties in a subsequent operating stage.
