Abstract (en)
[origin: EP1283301A2] The machine has a contactless sensor device (13) for determining the position of the sleepers (5) in conjunction with a displacement measuring unit (14) determining the position of the machine along the track rail (7), with centering of the working tools in dependence on the sleeper positions. The sensor device has a distance sensor (16) providing vertical distance values between the sensor device and the sleepers and between the sensor device and the track ballast (17), coupled to a control unit (15) determining the sleeper width (X) and the intermediate ballast gap (Y). An Independent claim is also included for a railway track maintenance method.
