The Eurail Pass, introduced in 1959 and formerly known as Europass or Eurorail Pass, is a rail pass which permits travel through 33 European countries on nearly all railroads and several shipping lines. The Eurail Group, based in Utrecht, is responsible for the marketing and management of the Eurail and Interrail passes. The company is owned by over 35 European railway and shipping companies. The Eurail Pass is available to non-European residents, and the Interrail Pass (introduced in 1972) is available to European residents. The passes, which provide access to 250,000 kilometres (160,000 mi) of European railway, are used by over 33,000 travellers annually.
