 The paper deals with a new rail cut test stand building reasons explanation. A project features definition is described. There is possible to perform the railway wheel tread profiles where research under the rail vehicle in operation condition simulation. This simulation is possible to execute on the test bench. An important feature of the research is the equivalent conicity change analysis. The paper outlines the stand operation principles of main structure components design and components parameter specification, the test control, data acquisition and data assessment.
