{"product_id":"5-inch-gauge-lner-a3-stock-code-3293","title":"5 inch gauge LNER A3","description":"\u003cp\u003eA 5 inch gauge LNER A1 Pacific, built to a simplified design with two  cylinders. Obviously intended for practical passenger-hauling rather than the  last word in attention to detail, nevertheless it captures the spirit of  Gresley's A1 as it first appeared, in later years to be rebuilt into the A3  super-Pacific form that is \"Flying Scotsman\" today.\u003c\/p\u003e  \u003cp\u003eCopper boiler, working pressure 80psi, feed by twin injectors with auxiliary  hand pump in tender. Smokebox regulator, rather ingeniously using a stainless 90  degree valve actuated by a rod running through a hollow stay from the backhead.  Two cylinders with piston valves actuated by Walschaert's valve gear with pole  reverser in cab. Mechanical lubricator on running board, rod operated drain  cocks, steam brakes.\u003c\/p\u003e  \u003cp\u003eThe boiler has had a twice pressure hydraulic test in the workshop and is  sound, the engine runs well on air.\u003c\/p\u003e  \u003cp\u003eThis engine sat for many years in a barn, along with a recently-arrived Britannia. I visited and saw both engines a couple of years ago, since when the A1  has been repainted. It will require a variety of jobs doing to recommission it  for work, but the chassis and boiler are both basically sound, it could be  improved as a rolling renovation.\u003c\/p\u003e  \u003cp\u003eLength\u003cbr\u003e  Weight with tender estimated 220 pounds\u003c\/p\u003e  \u003cp align=\"center\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019084616021,"sku":"3293","price":4950.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/3293-1.webp?v=1779901701","url":"https:\/\/stationroadsteam.com\/products\/5-inch-gauge-lner-a3-stock-code-3293","provider":"Station Road Steam","version":"1.0","type":"link"}
