Former French Railways SNCF "Mountain" (4-8-2) steamlocomotive 241 A 65, the largest coal fired in western Europe, with a train from Basel via Stein-Säckingen-Laufenburg-Full (AG)-Koblenz-Eglisau-Bülach to Zürich Altstetten, between Eglisau and Glattfelden, accelerating to track speed on a grade of 0.9 %, but with no visible smoke and only few sound. The four cylinder compound express train locomotive was built in 1931 by the Company Fives-Lille for the ETAT (Chemins de fer de l’État). Despite the impressive large driving wheels (diameter 1950 mm or 76.77 inches) she was built for "only" 110 km/h (68.35 miles per hour), today in Switzerland she is allowed to go 100 km/h. She is operational again in Switzerland since 1996 for the association 241 A 65 and based in Full (AG).
