Stuttgarter Straßenbahnen

What Stuttgarter Straßenbahnen does

Stuttgarter Straßenbahnen AG (SSB) is the primary municipal public transport operator in Stuttgart, Germany, operating Stadtbahn (light rail), bus, and rack railway (Zahnradbahn) services across the Stuttgart metropolitan area. Founded in 1889 and structured as a public limited company (Aktiengesellschaft), SSB is integrated within the Verkehrs- und Tarifverbund Stuttgart (VVS) tariff association, coordinating fares, schedules, and ticketing with regional operators. The company serves daily commuters, students, seniors, social welfare recipients, corporate clients via the DeutschlandTicket Job program, tourists, and event-goers through a broad portfolio including the DeutschlandTicket (€58/month as of 2024), time-based subscriptions, single-ride tickets, KombiTicket event bundles, and the on-demand SSB Flex ride service operated in partnership with GHT Mobility GmbH.

SSB's technology stack comprises proprietary digital channels (SSB Move, polygo, SSB Flex apps), the CheckIn-BeOut automatic fare system using GPS, Bluetooth beacons, and activity sensors, station ticket machines, and a planned 2027 app relaunch. The company is also engaged in a major rail digitalization program, with Alstom retrofitting 215 S-Bahn Stuttgart electric multiple units with European Train Control System (ETCS) and highly automated control systems. Distribution spans two owned customer centers (with a third consolidating location planned at Lautenschlagerstraße 2), over 350 VVS sales points, digital channels, telephone support, and B2B employer partnerships. Heritage leisure assets (Killesbergbahn narrow-gauge railway, Straßenbahnmuseum) provide additional revenue diversification and community engagement.

The business model is dominated by passenger fare revenue and recurring subscriptions, supplemented by event-driven KombiTicket arrangements (with VfB Stuttgart, Staatstheater, Landesmesse Stuttgart, Porsche Arena, Stuttgarter Philharmoniker, and others), on-demand ride fees from SSB Flex, and ancillary leisure revenue. Pricing is fully embedded within the VVS zone-based tariff system. Leadership comprises a Vorstand board led by Thomas Moser as Speaker alongside Mathias Hüske and Annette Schwarz, with Dr. Frank Nopper serving as Aufsichtsratsvorsitzender (Chairman of the Supervisory Board).
