The European Rail supply industry was formerly represented by three associations: AICMR (Association Internationale des Constructeurs de Matérial Roulant), AFEDEF (Association des Fabricants Européens d'Equipements Ferroviaires), CELTE (Constructeurs Européens des Locomotives Thermiques et Electriques), all were based in France

With the creation of the single market in 1993, there became an urgent need to focus on European transport matters, so the three associations decided in 1991 to merge into UNIFE, the Union of the European Railway Industries.

In 1992, UNIFE moved to Brussels. Today it directly represents nearly 60 leading European companies responsible for the design, manufacture, maintenance and refurbishment of guided land transport systems, subsystems and related equipments.

UNIFE has 16 National Organisations as associated members representing another 900 railway supply companies.

The European rail supply industry generates around 60 Billion Euros in revenue per year and employs 130 000 people. UNIFE members manufacture 70% of the world-wide production of rail equipment.
