Abstract
In a method for renewing sleepers of a track formed of rails and the sleepers, the placement of skids, which support a machine frame of a track-building machine on the sleepers, is preceded by the machine frame being intermediately supported on the sleepers. The two rails are then distanced from one another, while avoiding a breakage separation, in a track section that includes both the region of the skids and the intermediate support. After supporting the machine frame on the skids, the intermediate support is lifted off the sleepers and work is begun.

A method for renewing sleepers of a track that is formed of rails and the sleepers, the method comprising:
- providing a track construction machine with a machine frame and skids configured to support the machine from on the sleepers;
- prior to placing the skids on the sleepers, supporting the machine frame on the sleepers or on a track bed with a vertically adjustable intermediate support;
- subsequently spacing the rails apart from one another in a track transverse direction extending perpendicular to a track longitudinal direction, while avoiding a separation of the rails, within a section of the track that includes both a region of the skids and of the intermediate support;
- and
- supporting the machine frame on the skids, subsequently removing the intermediate support from the sleepers or the track bed and starting a forward travel while renewing the sleepers of the track.
