NMBS/SNCB is an autonomous government company, formed in 1926 as

successor to the Belgian State Railways.

In 2005, the company was split up  into three parts: Infrabel, which manages the railway infrastructure, network operations and network access, the public railway operator NMBS/SNCB itself to manage the freight (B-Cargo) and passenger services, and NMBS/SNCB-Holding, which owns both public companies and supervises the collaboration between them.
