The
Hafen-Dampfschifffahrt AG (HADAG) was founded on 8 August 1888, and the Free and Hanseatic City of Hamburg granted the concession to operate ferries in the
Port of Hamburg. In 1897, the HADAG owned 47 ferries and took over the smaller
Jollenführer Dampfer GmbH. With opening of the
Elbe tunnel in 1911, the HADAG line
Landungsbrücken —
Steinwerder lost 259,000 passengers p.a.. In 1918, with the end of the concession, the HADAG wanted to rise the fare price. The city of Hamburg refused and the company was in danger of liquidation. On 23 October 1918, the city of Hamburg acquired the HADAG. Later it became a subsidiary for the
Hamburger Hochbahn (HHA). In 1928 the HHA and HADAG established a shared fare for the trains, trams, and buses of the HHA and the ferries of the HADAG. In the 1950s, the HADAG operated a ferry to England and to the islands
Heligoland and
Sylt. In 1966, the last steam ferries were taken out of service. Until 1983, the HADAG owned the cruise ship
MS Astor. ==Operations==
