A cutting insert for profile turning, in particular for wheel profile turning, includes an upper surface, a lower surface, and side surfaces. At the transition from the upper surface to the side surfaces two cutting edges are formed for machining a workpiece and two further edges each having two ends. The two cutting edges are designed part-circular in shape and each extend from one end of one of the two edges to the opposite end of the other of the two edges. Also described is a cartridge for holding a cutting insert, the cartridge being mountable on a machine tool. The cartridge has a main seating surface having a plane angle (&#x3b1;) of greater than 90&#xb0; to the axis of rotation (D) of the workpiece.

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.
