A common reference base (13) of a track-position measurement system (10) consists of a single measurement chord (14), which is arranged centrally between the rails (4) and extends in the machine longitudinal direction. On a central track-position measurement unit (12), two sensors (16) for determining a longitudinal height and for determining a versine are arranged, which sensors each contact the measurement chord (14). Each track-position measurement unit (12) has two laser scanners (17), which are associated with respective rails (4), for scanning in a y-axis extending normally to a rail longitudinal direction and in a z-axis extending in a vertical direction. Thus, a simplification of the track-position measurement system (10) with increased accuracy can be achieved. |
