Olten
I've put a few more of this spring's photos online at Fotopic.Net. These were taken at Olten in northern Switzerland, junction of five routes, north to Basel, south to Luzern and the Gotthard route, southwest to Bern and the Lotchberg pass, West to Neuchatel and Geneva, and east to Zurich. It's a busy place with a wide variety of traffic on it's six running lines.
I saw everything from the veteran Ae6/6 locos dating from 1952 to the modern ICN intercity multiple units. Even a Swiss Express push-pull set. As well as SBB passenger and freight, there's also freight traffic from private railways RM and BLS. It's a real hotspot; a pity I visited the place on a rather dull and overcast day.
