Boiler fed by injector and mechnical pump with bypass, auxiliary  hand pump mounted on side of tender. Stainless steel grate. Single cylinder,  slide valve actuated by Stephenson's valve gear. Two speed transmission with  winch behind nearside rear wheel and tender-mounted fairleads.\u003c\/p\u003e  \u003cp\u003eAs with all kit-build engines, the parts benefit considerably from  sympathetic fettling on assembly and careful checking at all stages for free  running. There is damage to the chimney base casting, where the model was moved  by somebody pulling on the chimney - not recommended. There is some surface rust  which comes off easily.\u003c\/p\u003e  \u003cp\u003eLength 46 inches\u003cbr\u003e  Height 36 inches\u003cbr\u003e  Width 20 inches\u003cbr\u003e  Weight 400 pounds\u003c\/p\u003e  \u003cp align=\"center\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019105587541,"sku":"2811","price":5500.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/2811-1.webp?v=1779901900","url":"https:\/\/stationroadsteam.com\/products\/4-inch-scale-ruston-traction-engine-for-completion-stock-code-2811","provider":"Station Road Steam","version":"1.0","type":"link"}
