A 5 inch gauge New York & Hudson River Railroad 4-4-0, an older engine completed in 1988, built to a good standard and dismantled in recent years to overhaul and repaint. Designed by John Clarke, we get these in now and again - always been impressed by how well they go, I think it's a particularly good looking design (although granted you do have to like nineteenth century "Wild West" engines - I do, but they're a bit of a Marmite thing). There is club boiler history with the engine, last test dated 2009.
There are pictures of a particularly good one of these we sold back in 2009 in the archive here, if you want to see what the finished thing looks like.
