The Altona–Blankenese railway is a railway line to the west of Hamburg. It starts at the Altona station and runs through Othmarschen to Blankenese station. This section of line was opened in 1867. 16 years later the line was extended to Wedel. 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.
