History
The first part of the line was opened on 1 December 1914 from Kellinghusenstraße to Ohlsdorf. In 1920, the new branch from Wandsbek-Gartenstadt (Walddörfer railway) to Volksdorf opened; the two branches to Großhansdorf and Ohlstedt followed in 1921 and 1925. Also in 1921, the Langenhorn railway to Ochsenzoll was established. On this line, there had been a preliminary service with steam trains since 1918.
On 2 June 1929 the first part and on 25 March 1931 the second part of the KellJung line to Jungfernstieg was added. From 1960 to 1963 the line was built through the city center to Wandsbek-Gartenstadt, which completed the U1 line, connecting the branch to Volksdorf. In 1969 and 1996 the Langenhorn railway was extended to Garstedt and Norderstedt Mitte, using existing or re-built stations of the Alster Northern Railway, which is today part of the AKN network.
