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.[2] Many lines were built alongside roads, and carried considerable quantities of freight (especially timber and agricultural produce) as well as passengers.The non-electric network reached a peak of approximately 3,938 kilometres (2,447 mi) in 1925, but soon parts started to close as usage of buses, lorries, and electric trams increased.Political federalism within Belgium from 1980 onwards saw the splitting of many national institutions into separate bodies for Flanders, Wallonia, and the Brussels-Capital Region.De Lijn inherited the tram systems in Ghent and Antwerp (including the Pre-metro), operated previously by local companies MIVG and MIVA respectively, and the coastal tramway.
