Who we are

Founded in 1950, the UIP – International Union of Wagon Keepers, with its seat in Brussels, is the umbrella association of national associations from fourteen European countries, thus representing more than 250 freight wagon keepers and ECMs with more than 238’000 freight wagons, performing 50 % of the rail freight tonne-Kilometres throughout Europe. The UIP represents the members’ concerns at international level. By means of research, lobbying and focused cooperation with all stakeholders and organisations interested in rail freight transportation, the UIP wants to secure on the long term the future of rail freight transport.

What we represent

As the voice for more than 238’000 rail freight wagons, we represent one of the most important resources for rail freight transportation in Europe.  At UIP our priority is to support wagon keepers and those who have a role as Entities in Charge of Maintenance in achieving higher economic performance and adapting to modern logistics chain requirements.

In economic terms, UIP stands for:

  • a 12bn € private investment in existing rolling stock
  • a yearly 400 – 500mio € private investment in new rolling stock

Our strategic objectives

Looking at improving the attractiveness and competitiveness of rail freight services in Europe, we aim to:

  • increase the awareness among policy and decision makers of the role of the wagon keepers in the railway system and in the logistics supply-chain
  • develope an economically sound long-term vision for investments in rail freight wagons
  • ensure fair market conditions between transport modes and fair intramodal competition (freight vs. passenger)
  • develop a common culture for efficient exchanges of information and relevant data among the actors in the railway system and the supply chain, including freight customers
  • promote regulatory stability and consistency at EU level to ensure wagon interoperability and safety while respecting the lifecycle of the assets (25-35 years)
