Bremerhaven–Bederkesa railway line, Heritage railway line between Bremerhaven and Bad Bederkesa, Germany

The Bremerhaven–Bederkesa railway is a 17.6 km standard-gauge line branching from the Bremen–Bremerhaven railway at Bremerhaven-Speckenbüttel and running via Langen, Debstedt, Knüppelholz, Drangstedt and Bad Bederkesa. The intermediate stations received small single-storey service buildings similar to those on the Cuxhaven line; Langen also had a waiting hall later converted into a goods shed.

The railway opened in 1896 and served passenger transport for more than 70 years before ending in 1968. Freight services continued afterward until the line closed completely in 1993 and was later revived as a heritage railway.

The heritage railway is run by the Museumsbahn Bremerhaven–Bederkesa e. V., founded in March 1990 on the initiative of Bederkesa's then Samtgemeindedirektor Wilfried Habenicht and Bremerhaven railway enthusiasts. The association aims to recreate the railway operations of the 1950s. Its trains run from Bederkesa via Lehe, Hauptbahnhof and Wulsdorf to the 'Schaufenster Fischereihafen' station.

The line runs 17.6 km from Bremerhaven-Speckenbüttel to Bad Bederkesa. On operating days the heritage railway makes three trips from Bederkesa to Bremerhaven-Fischereihafen, and only the first continues to Bremerhaven Hauptbahnhof. The association's vehicles are kept in a shed in Bederkesa, opened in 2007.

The V 36 134, which opened the heritage service in October 2000, has stood out of use in Bad Bederkesa since a machine failure in December 2004; the association no longer plans to restore it. Since 2006, Elbe-Weser-Verkehrsbetriebe V 100 locomotives from Bremervörde have hauled the trains instead.
