2014 was the first year since the liberalisation of the freight and international passenger traffic markets where the number of rail companies operating on the Belgian network fell. At the end of 2014 Infrabel had 15 customers, of whom 13 had been active.
For freight transport there were 13 approved operators at the end of 2014, of whom 11 were actually running trains. These were SNCB-Logistics, CAPTRAIN, CFL-Cargo, Crossrail Benelux NV, DB Schenker Rail Nederland N.V., EuroCargoRail, Europorte, RailTraxx, Rotterdam Rail Feeding, SNCF Fret and Trainsport. The operators ERS and PKP Cargo were approved, but did not make use of the rail network in 2014. Compared to 2013, operators Rurtalbahn and Thello no longer had a safety certificate for operating on the Belgian rail network.
In May 2015, high-speed train operator Thalys, an international partnership between the railway operators SNCF, Deutsche Bahn, NS and SNCB became a full passenger operator. Once Thalys became independent in Belgium and France, Infrabel had 16 operators.
