On Swiss National Day, 1 August, the Koblenz Depot and Rail Vehicles Association (Depot und Schienenfahrzeuge Koblenz) (DSF) organized an extra train "Around the Säntis" with the beautiful former SBB express train from the 1970s. The Re 4/4 II # 11173, delivered by SLM and BBC in September 1970, pulls three 2nd and 1st class standard coaches along Lake Walen near Tiefenwinkel, between Murg and Mühlehorn. Train 31133, under the responsibility of the railroad company Oensingen-Balsthal-Bahn, ran from Koblenz via Turgi-Zürich Altstetten-Kloten-Winterthur-Romanshorn VL to Rorschach for a longer stopover. Then the journey went as train 31145 via St.Margrethen-Buchs SG-Sargans-Ziegelbrücke-Zürich Altstetten-Turgi back to Koblenz.
