TheOffenbach-Bieber–Dietzenbach railway branches in Offenbach-Bieber station from theRodgau Railway (German:Rodgaubahn) and runs viaHeusenstamm toDietzenbach in the German state ofHesse. The line is integrated into theFrankfurt S-Bahn network. It is served byline S 2.

The Offenbach-Bieber–Dietzenbach line was opened on 1 December 1898, following the opening of the Rodgau Railway in 1896. It was the result of continuing efforts at the local level since about 1870 to open up the area south ofOffenbach am Main with a railway, but which was only adopted by theGrand Duchy of Hesse very slowly. So it took until 1888 for the government to finally give its approval and it took another ten years until the first train ran.

The first trains were steam hauled; after the Second World War trains were increasingly hauled by diesel locomotives. The importance of the connection lay in the growing commuter traffic from thedistrict of Offenbach, especially for those working in the leather goods industry in Offenbach.

On 18 June 1982, passenger services were closed to Dietzenbach.

The establishment of anS-Bahn operation on the track was considered in the late 1950s. It was not, however, until 23 March 2001 that the line to Dietzenbach began to be reconstructed as a double-track electrified line of the Frankfurt S-Bahn network. A proposed extension of the line toRödermark-Ober Roden via Rödermark-Urberach failed as it was found not to be economically justified. The last kilometre between Dietzenbach Mitte and Dietzenbach stations was built as a single track. The last station is nearSpessartviertel (Spessart quarter, formerly calledStarkenburgring), an area of high-rise residences. As a result of some incidents, the ceramic insulators on the catenary masts on the line near the housing were protected with bullet-proof metal plates.

S-Bahn operations began on line S 2 (Niedernhausen–Dietzenbach) at the beginning of the 2003/2004 timetable on 14 December 2003. The line is operated byDB Regio as part of theRhine-Main S-Bahn network. After the conversion of the line for S-Bahn operations there remained only one siding on the line; it is in Dietzenbach-Steinberg and is used by a fruit wholesaler.^[2][3]
