Rostocker Straßenbahn AG

Rostocker Straßenbahn AG (RSAG) is the public transport operator responsible for tram and bus services in the city of Rostock and its surrounding area. The company moves passengers across the urban network, providing regular scheduled services that connect residential districts, commercial centres, and key points of interest. In addition to vehicle operations, RSAG manages ticket sales through various channels, including online portals and physical sales points. It also operates digital passenger information systems that display real‑time arrivals and service updates.

RSAG functions as part of the Verkehrsverbund Warnow (VVW), the regional transport association that coordinates fares and timetables across multiple operators in the Mecklenburg‑Vorpommern region. Through this cooperation, passengers can use a single ticket for journeys that combine RSAG services with those of neighbouring bus and rail providers. The company’s operational footprint covers the Rostock metropolitan area, where it supports daily commuting, school travel, and leisure mobility. By integrating with the VVW, RSAG contributes to a seamless regional mobility offering.

Distinguishing characteristics of RSAG include its role as a municipal enterprise focused on sustainable urban mobility, with an emphasis on reducing reliance on private cars. The company maintains an ABO portal for subscription management, which was highlighted during the November 2023 cyber incident when the portal was temporarily unavailable. RSAG also provides digital platforms for customer communication and sales, which were affected by the same attack, prompting the implementation of cash‑only transactions at service points. Its close collaboration with data protection authorities and external cybersecurity experts under GDPR obligations demonstrates a commitment to safeguarding passenger information.

Structurally, Rostocker Straßenbahn AG is owned by the city of Rostock, operating as a publicly owned transport company under municipal oversight. This ownership model aligns the company's objectives with local public policy goals concerning environmental protection and accessible transportation. As a municipal entity, RSAG reports to the city’s administrative bodies and follows regulations applicable to public utilities in Germany. The organisation’s governance ensures that service decisions reflect the needs of Rostock’s residents and visitors.
