Until the opening of the long Western Entrance to the Riedbahn ("westlichen Einführung der Riedbahn", WER) to Mannheim Hauptbahnhof in 1985, trains from Frankfurt came from the south to reach Mannheim and had to reverse to continue south towards Heidelberg or Karlsruhe on the Rhine Valley line. Some TGV and Intercity-Express (ICE) services continue to use the eastern branch of the Ried Railway to cross the Rhine without reversal. Almost all regional trains run on the new western approach; Mannheim-Käfertal station is currently operated by one Regionalbahn service each day. The eastern Ried Railway has 180 pairs of trains each day, mainly freight traffic.
