"Voralpen Express" (VAE) 2580 from St.Gallen to Luzern (this day to Arth Goldau only because of track work) is crossing the 282 meter long Weissenbach vaiduct of the former Bodensee-Toggenburg Bahn (BT), now the Südostbahn line (Romanshorn-) St.Gallen-Wattwil. Since a few days, the power of the train is very special and rare, with railcar RBDe 561 # 082 in front and locomotive Re 446 # 016 in the rear. Usually there are RBDe 561/Re 456/Re 446 in front and rear, but not mixed.
