National Company of Light Railways

The National Company of Light Railways (Dutch: Nationale Maatschappij Van Buurtspoorwegen, abbreviated as NMVB; French: Société Nationale des Chemins de fer Vicinaux, abbreviated as SNCV) was a state-owned transportation provider which comprised a system of narrow-gauge tramways or local railways in Belgium, which covered the whole country, including the countryside, and had a greater route length than the mainline railway system. They were 1,000 mm (3 ft 3+3⁄8 in) metre gauge and included electrified city lines and rural lines using steam locomotives and diesel railcars; half the system was electrified.

The company gradually switched to buses and dismantled the tram tracks. Only the coastal line, the Charleroi metro, and the short line to the caves at Han-sur-Lesse are still in commercial use; four museums hold significant collections of rolling stock, including the museum at Schepdaal and the ASVi museum in Thuin. The longest (11 km (6.8 mi)) and oldest (40 years) tourist tramway is the Tramway Touristique de l'Aisne (TTA), between Érezée and Dochamps. A sponsoring group called "Tramania" has supported various tramway preservation initiatives for 13 years, in particular by financing the construction of the Thuin museum and car restoration for TTA.
