0-3-0 tank engine number 5 of the former Sihltalbahn, built in 1899 by SLM Winterthur, is preparing for the special "searching the easter egg" to Silbrugg-Zug, in front of the little shed in Sihlwald on the SZU Railway (Sihltal Zürich Uetliberg Bahn). The little engine is called "Schnaaggi-Schaaggi", which means "Slow John" and belongs to the association Zürcher Museums Bahn (ZMB) today.
