Opened in 1875, Ghent's tramway lines extend approximately 30 km. The tramway has one stop in a bridge underpass below the main railway station. However, it is not a subway.
Trams in Ghent allegedly almost met the fate of trams in other Belgian cities, notably Charleroi, where they were replaced with metros the municipalities could not afford, and so left for dead. City planners eyed taking out the trams and replacing them in subways from dried up canal beds. Whether through inertia or political infighting, the dirty deed was never done.
