After the closure of the Charleroi city tram, several trams were preserved, albeit without any real concrete purpose.
3 of these preserved trams were stored at a local railway museum (without catenary) in France in 1982.
The first vehicle is the 423, the numbers of the other 2 vehicles are unknown to me.
