Ploiesti, Romania
R.A.T.Ph. (Regia Autonoma de Transport Public Ploiesti)
This building houses the rectification station for the former tram line 104. The equipment is still in one piece, but it can't be use, because there are no tram running anymore in that area, and the building is far from the other tram and trolleybus lines.
