The Council of Europe and the International Union of Railways (UIC) joined forces on 16 December 1994 to set up the Solidarity Fund for Youth Mobility, a fund for the mobility of disadvantaged young people. For every Inter Rail Card sold, one EURO will be donated by the International Union of Railways to the funding of projects involving Europe's young and least well off, enabling them to attend international activities, taking them on journeys of cross-cultural contact and discovery. The fund caters solely for young people from underprivileged backgrounds or economically underdeveloped areas and is intended to cover the rail travel (2nd class) of these young people participating in international educational activities. It does not assist tourist travel. To qualify for assistance, projects must involve at least two countries and a minimum of ten people.
