Exactly on the day 125 years after the inauguration of the Oensingen-Balsthal Railway (OeBB), which is only about 4 kilometers long, a very nice and interesting festive programme was organized. All scheduled passenger trains on the line were run by the "reserve push-pull train" of the OeBB, instead of the rented "Domino" train of the SBB as usual. In Klus, train 26055 of the line S22 from Oensingen to Balsthal can be seen, with privately owned, former SOB/SBB locomotive Re 430 # 350 (Re 4/4 II # 11350), former BLS "Jumbo" articulated intermediate car and cab car ABt # 197 former Südostbahn/Depot und Schienenfahreuge Koblenz (DSF). In the future, instead of the Re 430 # 350 (Re 4/4 III # 11350) the new railcar RBe 546 # 109 former Montafonerbahn will be used. In the background Alt-Falkenstein fortress from the 13th century.
