The trains will be ordered as required to operate services tendered by the state government. In order to bid for these contracts, Sweg must first conclude a framework agreement with a rolling stock supplier to ensure it can provide the train fleet required in time for the start of operations.

Sweg already operates two Bombardier Talent 2 EMUs on the Bad Krozingen - Münstertal line, which is part of the Breisgau S-Bahn network.

Sweg is 100%-owned by the state of Baden-Württemberg.
