The Union of Tramway and Municipal Transport Workers (Dutch: Belgische Centrale Van Tram- Buurtspoorweg- en Autobuspersoneel, BCTBAP; French: Centrale Belge du personnel des tramways, vicinaux et autobus, CBPT) was a trade union representing public sector transport workers in Belgium.
The union was founded in 1919 as the National Federation of Tram Personnel.
In 1945, it was a founding constituent of the General Federation of Belgian Labour.
In 1947, it affiliated to the Belgian Union of Transport Workers, but it split away again in the early 1950s.
[1] By 1967, it had only 6,309 members, and the following year, it merged into the General Union of Public Services.
