Passenger services to Laupheim town, branching off the Southern Railway at Laupheim West on the Laupheim–Schwendi railway, which were closed in 1983, resumed on 30 May 1999 as an hourly Regionalbahn service from Langenau via Ulm to Laupheim town or Biberach (Riss), with regional shuttles using class 650 diesel railcars. Interregio-Express (IRE) line 26 from Saarbrücken via Mannheim, Stuttgart, Ulm and Friedrichshafen to Lindau, running every two hours, opened in 1990, was reinstated on 15 December 2002 and an additional IRE service, also running every two hours, ran on the Stuttgart–Ulm–Lindau section of the route. Later, the IRE network was further expanded.
