Abstract
A method for calibrating a device for measuring tracks having a track-driveable track-measuring car with a lifting and lining device and track-position measurement sensors measuring the height, direction and superelevation of the rails of the track using the machine frame as a reference zero line. A lifting and lowering device is associated with the track-measuring car. A calibration device is associated with the machine frame the track-measuring car, for calibrating the sensors, is first lowered from a parking position, in which the track-measuring car is lifted from the track, onto the track or into an intermediate position. Calibration stops are moved by an actuator from an idle position into a calibration position, against which the track-measuring car is subsequently raised and applied. The values of the track-position measurement sensors are read out and stored in the measurement system as calibration values, and the track-measuring car is lowered onto the track.
