In september 2014 already, the Re 6/6 # 11626 "Zollikofen" (Re 620 # 026), then in red colors, got "moustaches" on both fronts, similar to the Ae 6/6 # 11401 to # 11425 ("Kantonslok"), as decoration probably for the last trip of an engineer prior retirement. In september 2019, the Re 620 # 026 got a large revision R3 with the new blue/red Cargo-colors in Bellinzona. Afterwards, surprisingly, the "moustache" were added again. The locomotive pulls the empty tank car train 66522 from Niederglatt via Zürich Oerlikon-Zürich Altstetten-Brugg-Olten-Biel to Cornaux (Cressier refinery), through Twann on the shore of Lake Biel.
