On Switzerlands national day, first of august, electric railcar "Churchillpfeil" (Churchill Arrow) is leaving Zürich main station for a roundtrip on the left and right shore of Lake Zürich, then heading for Lake Zug and Lake Lucerne for the firework at Brunnen. RAe 4/8 1021 was built in 1939 and withdrawn the first time in 1985, but bought by Alby Glatt (Intraflug) and stored in Germany. Later rebuilt and put in service again by the Mittel-Thurgau-Bahn, the vehicle came to SBB passenger division after the insolvency of the MThB.
