AAR is a system of public traffic in Aarau and its region using buses and narrow gauge (1000mm) railways. The "Wynental- und Suhrentalbahn" (WBS) could be surely named as backbone of this system. Here started WBS Be 34 from "main-station" of the company in Aarau. Please excuse lingual stumbling, but this station is placed behind main-station of SBB (oder wie de' Koelsche sagen würd': Auf de' schä Sick). Shot on 4th of August 2005.
