Südostbahn ordered six more Traverso trains and three Flirt trains from a framework agreement with StadlerRail in February 2023. The Traverso trains have already been delivered and are in operation, while the first Flirt of the repeat order, RABe 526 # 011, is on a test run from Sulgen to Romanshorn, passing the pond in Riedt between Sulgen and Erlen.
