The tramway in Charleroi (South Belgium, approx. 200,000 inhabitants) is largely developed as a light rail system, traced underground or on bridges and is marketed as a metro. It operates on a 30 kilometre long, metre-gauge network and is operated by → TEC (Transport En Commun)
In the 1970s, it was planned to convert the network to a "real" subway, but this completely disregarded the needs of transport. Further expansion was already halted in the 1980s due to financing problems. As a result, the infrastructure today is completely oversized: At many stations there are unused platforms, the ones in operation are often many times longer than the trains that stop there. A complete line never went into operation and becomes more and more desolate. An important gap in the inner city was filled in 2012 - again as a "classic" tram line.
