Test run of Thurbo from Sulgen to Romanshorn, running along the pond at Riedt near Erlen. Articulated lowfloor train RABe 526 # 769 (AKL=automatic coupler long version) and RABe 526 # 284 in multiple control. Thurbo has taken over 13 vehicles from SBB (RABe 526 # 260 to # 265 and # 280 to # 286), which were built for RM (Regionalverkehr Mittelland) in 2003/2004, came to BLS in 2006 and finally went to SBB in December 2013. They were used in the Biel/Jura area. In 2018 they were taken over by Thurbo, but for the time being they are still used in the Jura. Now they are used by Thurbo, but a mixed use with the previous RABe 526 # 701 to 805 was not possible so far, especially because of the different customer information system. With the test runs, the mixed use was now tested.
