The Belgian State Railways Type 7 (originally the Type 8 bis), later known as the NMBS/SNCB Type 7, was a class of compound locomotives built between 1921 and 1924.
The class was used to work heavy passenger trains operated by the Belgian State Railways, and its successor, the National Railway Company of Belgium (NMBS/SNCB), which was established in 1926.
One member of the class, no. 7.039, has been preserved by the NMBS/SNCB for display at Train World, the Belgian national railway museum.
