Hochbahn

What Hochbahn does

Hamburger Hochbahn AG (HOCHBAHN) is the municipal public transport operator of the Free and Hanseatic City of Hamburg, wholly owned by the city and governed through HGV Hamburger Gesellschaft für Vermögens- und Beteiligungsmanagement. Founded in 1911 and operating the U-Bahn since 1912, the company runs Hamburg's U-Bahn subway network across the U1–U4 lines (with U5 under construction), a citywide bus network, and — through subsidiaries — Alster and Elbe ferry services (HADAG), tourism boats (ATG), vehicle maintenance (FFG), station security (HHW), and the dedicated U5 project company. The company employs 6,600+ qualified staff, serves approximately 1.2 million passengers per day, and operates 93 U-Bahn stations (over 90% barrier-free) along with the Barmbek depot and main workshop.

Technology is a core strategic priority: HOCHBAHN is building MOSAIC, a Mobility-as-a-Service back-end platform that underpins the hvv switch app and is being co-developed with BVG Berlin into a nationwide Germany mobility app. The fleet is being modernized with the DT6 next-generation U-Bahn (up to 370 vehicles procurable through 2045) and the U-Bahn100 automation program targeting 100-second intervals on the U2 and U4 lines via GoA2. The fully automatic U5 — Germany's largest underground railway project — is planned to launch the Bramfeld–Borgweg segment around 2033 at 90-second headways. The bus fleet of 432 electric vehicles (39% of fleet) is on a binding path to 100% zero-emission by the early 2030s via 590 additional e-buses ordered (350 by 2030, 240 by 2031), supported by autonomous-bus pilots ALIKE (Holon), 3plus3 (autonomous line operation), and the HEAT project.

The business model rests on a 2019 direct award contract (Direktvergabe) from Hamburg covering 10 years for major bus services and 22.5 years for all U-Bahn services, with passenger fares collected through the regulated hvv (Hamburger Verkehrsverbund) transport-association tariff. Capital expenditure on U5, DT6, fleet electrification, and digitalization is funded through a mix of public subsidies, parent-company result balancing via HGV, and ICMA-aligned Green Bonds — the latter qualifying for S&P's "Dark Green" Second Party Opinion and enabling HOCHBAHN's AAA Fitch credit rating. Auxiliary revenue streams flow through 12 wholly-owned subsidiaries spanning ferry operations, advertising, real estate, building services, hydrogen promotion (hySOLUTIONS), and central bus-station operations (ZOB Bus-Port Hamburg).

HOCHBAHN operates as Hamburg's public transport authority, managing a multi-modal urban mobility system comprising U-Bahn (metro/subway) rail services, bus operations, and emerging autonomous transport solutions. The core offering includes the U-Bahn network (U1-U4 lines with U5 under construction), an expanding electric bus fleet, and pilot autonomous bus programs (ALIKE, 3plus3). The technology portfolio centers on the MOSAIC Mobility-as-a-Service platform powering the hvv switch app, enabling integrated access to trains, buses, bike-sharing, car-sharing, and ridepooling. Major infrastructure projects include the fully automatic U5 subway (Germany's largest metro project), U-Bahn100 automation enabling 100-second train intervals, and DT6 next-generation metro vehicles. The company is transitioning to 100% zero-emission buses by the early 2030s.
