The Rostock S-Bahn (German: S-Bahn Rostock) is a S-Bahn (suburban railway) network in Rostock in the German state of Mecklenburg-Vorpommern. It consists of three lines with a total length of about 90 km. Line S1 runs from Rostock Hauptbahnhof (main station) to Warnemünde within the Rostock urban area. S-Bahn operations started in 1970s. Later, the lines to the north-east to the port (Seehafen) of Rostock and to the south to the town of Güstrow via Schwaan were included in the S-Bahn network. The line to the port was discontinued in 2012, but at same time the line to Güstrow via Laage was included as line S3 of the S-Bahn. Until 2014 they were mainly operated as push–pull trains with double-deck coaches. Since then all lines have been operated with new Bombardier Talent 2 railcars.
