It is now used by lines S1 and S11 of the Hamburg S-Bahn and was part of the first electrified suburban railway in Germany.

The line then runs to the stations of Iserbrook, Sülldorf, Rissen and finally, the terminus at Wedel.

Between 1911 and 1914 the Blankenese–Marienhöhe Trackless Railway (Gleislose Bahn Blankenese–Marienhöhe), an early trolleybus operation, ran from Blankenese station.

In 1907 the line was electrified with overhead wires at 6.3 kV 25 Hz alternating current.

In 1934, the Urban and Suburban Railway was renamed the S-Bahn and converted to direct current operations, using side-contact third rail and a voltage of 1.2 kV.

Sidings also connected to the Ottensen industrial railway and the Unilever margarine factory, using the Rollbock system.
