Niles Canyon Railway on the Edge of Silicon Valley. Same place where Charlie Chaplin filmed "The Tramp". The line currently runs between the Niles district of the city of Fremont (Where Tesla Motors builds its Model S sedan) to Sunol, but is currently being extended to the city of Pleasanton, CA.
What makes it a mallet (named for it's inventor, Anatole Mallet) is that the rear wheels are attached to the frame and the front wheels are free to pivot, to allow it to go around sharp curves. As well, one set of wheels is driven by high pressure steam cylinders while the other, low pressure cylinders, use the "recycled" steam exhausted from the high pressure cylinders. Great capture
