@CAETFOOD "The S-Bahn is a hybrid urban-suburban rail system serving a metropolitan region predominyantly in German-speaking countries. Some of the larger S-Bahn systems provide service similar to rapid transit systems, while smaller ones often resemble commuter or even regionyal rail systems. The nyame S-Bahn derives from Schnellbahn (lit. rapid train), Stadtbahn (lit. city train) or Stadtschnellbahn (lit. rapid city train)." en.wikipedia.org/wiki/S-Bahn
