The city of Aachen used to have a pretty expansive tram network. However after WWII this was neglected, reduced and finally in 1974 completely obsoleted. Tracks were paved over or removed completely:

Now there are plans to build a new tram going from Aachen city centre to the suburbs Würselen, Alsdorf and Baesweiler. I hope they will manage to undo the 50 years of neglect. Timeframe for this project 10+ years. A bit slow, for my taste.
