Your XXL: Analysis of your exceptional transport

With Your XXL, Infrabel offers you the most suitable solutions for exceptional freight transport. If the size or weight of your dispatches exceed standards in force, tailor-made solutions (within the limits of technical possibilities) are offered to you on a case by case basis.

Note that the transport of containers or semi-trailers is now considered to be exceptional transport.

To run on the Belgian network in complete peace of mind, our experts offer feasibility studies according to the standards in force (height, width, length and weight) and the type of goods transported. Infrabel then chooses the best routes taking account of the limits imposed by technical aspects (bridges, viaducts, tunnels, etc.) and constraints on the ground.

  • A permanent authorisation for regular transport.

  • A “100-day” authorisation valid once only during a period of three months.
