Abstract
A continuously advancing machine for track leveling, lining and tamping comprises a main frame, a single undercarriage supporting the main frame and the main frame having a portion projecting in the track direction from the single undercarriage, a drive connected to the single undercarriage for continuously advancing the main frame in an operating direction, a brake connected to the single undercarriage for stopping the advancing main frame, and an operator's cab, a control arrangement and a power plant mounted on the continuously advancing main frame. The machine further comprises a tool-carrying frame, an undercarriage supporting the tool-carrying frame on the track, the tool-carrying frame supporting undercarriage being widely spaced from the main frame supporting undercarriage and the projecting main frame portion being longitudinally displaceably supported on the tool-carrying frame, a drive for intermittently advancing the tool-carrying frame, tie tamping and track position correcting tools mounted on the tool-carrying frame within sight of the operator's cab, the tools including drives for operating the tools and the drives being actuated by the control arrangement, and a track position reference system connected to the control arrangement for actuating the drives of the track position correcting tools in response to the track position detected by the reference system.
