From 14 December 2003, the Rodgau Railway between Offenbach and Rödermark-Ober-Roden became part of the Rhine-Main S-Bahn, but the section between Ober-Roden and Dieburg was not included.

As a result, the diesel multiple units running on the Dreieich Railway to Ober-Roden (usually from Dreieich-Buchschlag) now continue to and from Dieburg.

In early 2009, work began on the elimination of the passenger level crossing and the construction of an underpass at Dieburg station.

Between the two lines at the eastern end of the station there is a siding leading into the industrial area of Dieburg.

The freight loading tracks east of the station building were dismantled as part of the construction of the new underpass.
