Bibliography

Describes the tread profiles of wheels with a diameter greater than or equal to 330 mm used on vehicles running on European standard gauge track to fulfil interoperability requirements. These profiles apply to new wheels, whether free-standing or assembled as wheelsets, as well as to wheels that require reprofiling during maintenance. Any profile that does not conform to this standard shall only be used following agreement between the train operator and the infrastructure manager.
