A wheel set for a rail vehicle, in particular for a locomotive, includes two track wheels which are connected by a wheel axle mounted in two wheel set bearings. Each wheel set bearing includes a cast bearing housing, which is closed by an outer housing cover and an inner pressure ring. In addition, the bearing housing has a clamping position for engaging a tensioning device of a machine tool for machining the wheel set. Since the clamping position is integrated in the pressure ring, the clamping position can be easily cut to size and the bearing housing can be produced in a weight-optimized and cost-effective way in comparison to known bearing housings.

A portable apparatus for configuring a wheel associated with a track is provided. The apparatus is in a fixed position with respect to a rail associated with the track when in operation. The apparatus includes a tool configured to engage the wheel, a position system for positioning the cutting tool in at least two axis, and a computer control. The computer control is coupled to control the positioning system. The positioning system is controlled so that the wheel is configured in accordance with a profile.

An apparatus reconfigures or configures a wheel associated with a train. The apparatus comprises a tool configured to engage the wheel a compound slide system for positioning the cutting tool in at least two axes. The compound slide system is controlled so that the wheel is configured in accordance with a profile. The slide system can be moved mechanically and/or pneumatically and/or can use a mechanical profile. The apparatus can have a low profile and a low weight.
