Since December 2009, the new line S 5 has operated from Heidelberg Hbf on the Neckar Valley Railway and the Elsenz Valley Railway to Sinsheim or every hour on the Steinsfurt–Eppingen railway to Eppingen. Trains only occasionally stopped at the two Heidelberg halts of "Schlierbach/Ziegelhausen" and "Orthopädie" for scheduling reasons until December 2016 and only hourly after that. Line S 51 was opened in June 2010; this branches off in Meckesheim over the Meckesheim–Neckarelz railway and runs every hour to Aglasterhausen.
