    "body": "## Overview\n\nLine U3 is the ring line (Circle Line) of the Hamburg U-Bahn. It is 20.7 kilometres long and serves 25 stations. The line runs from Wandsbek-Gartenstadt via Barmbek into the ring, which leads through the city centre back to Barmbek. The first sections of the ring were opened in February 1912 – making them among the oldest sections of the Hamburg U-Bahn. After the line swap of 2009, the U3 is once again a ring line with a branch line to Wandsbek-Gartenstadt.\n\n## Operator\n\nThe operator is the [[organization_hamburger_hochbahn|Hamburger Hochbahn AG]].\n\n\n## History\n\nThe ring line was built from 1906 to 1912; its first section went into operation in February 1912 between Rathaus, Hauptbahnhof and Barmbek – making the U3 the oldest line of the network. With the opening of the line to Horner Rennbahn on 2 January 1967 and its continuation to Billstedt, the U3 no longer ran as a ring but as a diameter line until 2009. In the line swap of 2009, the eastern sections of the U2 and U3 beyond the Berliner Tor were exchanged; since then the U3 has again been a ring line with a branch to Wandsbek-Gartenstadt.\n## Stations\n\nStations in operating direction (ring line from Barmbek via the city centre back to Barmbek, connection to the branch line to Wandsbek-Gartenstadt):\n\nRing (Barmbek – Barmbek):\n\n- Barmbek\n- Saarlandstraße\n- Borgweg\n- Sierichstraße\n- Kellinghusenstraße\n- Eppendorfer Baum\n- Hoheluftbrücke\n- Schlump\n- Sternschanze\n- Feldstraße\n- St. Pauli\n- Landungsbrücken\n- Baumwall\n- Rödingsmarkt\n- Rathaus\n- Mönckebergstraße\n- Hauptbahnhof Süd\n- Berliner Tor\n- Lübecker Straße\n- Uhlandstraße\n- Mundsburg\n- Hamburger Straße\n- Dehnhaide\n- Barmbek\n\nBranch line to Wandsbek-Gartenstadt:\n\n- Barmbek\n- Habichtstraße\n- Wandsbek-Gartenstadt",
