Black and white, black and white on the Furka cogwheel steam railway
If I was ever a fan of rail transport, this HG 3/4 would have been my favourite.
Black smoke from the firebox, white steam from the pressure boiler.
A quick stop to tank water and coal, and on the track again!
Sharp your eyes from the Rhone glacier down into the valley and you might see it climbing up the steep track between the road and the Rhone river.
