Brilliant, Phil! Makes me want to go on the real thing.
Always interesting to see these open panorama cars when they're stored for winter (either in a station between Thusis and Tiefencastel whose name escapes me, or at Untervaz near Chur) - they usually have their Jim-jams on in the form of tarpaulins!
I leave mine out on the line to provide a splash of colour in winter, but usually need to give them a good clean when services resume. A drop of oil on the axles and off they roll again... Passengers spend the winter indoors tho!
