ABSTRACT:
A measuring instrument has a first section for rolling a wheelset under lateral guidance of the wheelset into a measurement section with an auxiliary rail for supporting the wheelset on the outer edges of its wheels and a third section for rolling out the wheelset into the railway track, with the first and third section of the measuring instrument also designed as track panels and for which the optical beam devices under the measurement section are intended. The first and third section of the measuring instrument are flexibly embedded in the ballast of the superstructure of the railway track, while at least one of the optical beam devices is mounted vibration-free on the formation of the railway track in a pre-determined position in relation to the measurement section of the measuring instrument with no contact to the other parts of the measuring instrument.
