VKM - Vehicle Keeper Marking Register

A Vehicle Keeper Marking (VKM) is an alphanumeric code, consisting of 2 to 5 letters (1). A VKM is inscribed on each rail vehicle, near the vehicle number. The VKM denominates the Vehicle Keeper as registered in the Rolling Stock Register. A VKM is unique in all countries covered by this TSI and all countries that enter into an agreement that involves the application of the system of vehicle numbering and vehicle keeper marking as described in this TSI. The railway Vehicle Keeper Marking Register (VKM Register) provides the unique VKM and name of all keepers (EU/OTIF). It is defined in Appendix 6 part 1 of [Decision 2007/756/EC] (https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:02007D0756-20140101). It is updated on a monthly basis and is available either in PDF or in Excel format. Since 2014, a joint OTIF/EU VKM Register is hosted by ERA and provides the VKM details in four languages (English, French, German, Russian).
