Big mistake, we got it loaded  and safely (as we thought) home, only to find on arrival back at Station Road  Steam HQ that the back wheels of the engine had gone straight through the bed of  the trailer.\u003c\/p\u003e  \u003cp align=\"left\"\u003eAs we speak, Jacksons at Lincoln are cutting out a new piece of  exterior ply from a specially ordered huge sheet in order to get a single 8 x 5  foot piece without a join (and, happily, Dal is still speaking to me).\u003c\/p\u003e  \u003cp align=\"left\"\u003eA 6 inch scale traction engine, substantially complete, from the  same builder as the 4 1\/2 inch Allchin currently in stock. Built along roughly  the same lines as an Allchin, it's basically a large, freelance engine although  of quite decent proportions.\u003c\/p\u003e  \u003cp align=\"left\"\u003eSteel boiler with expanded tubes, feed by mechanical pump. Cast  iron cylinder block, slide valve actuated by Stephenson's valve gear with pole  reverser on footplate. Mechanical lubricator, drain cocks designed for rod  operation, but currently missing operating linkage. Two speed transmission, all  by gears.\u003c\/p\u003e  \u003cp align=\"left\"\u003eThe builder only ever ran the engine on air, it runs well in  forward gear with a healthy bark to the exhaust, reverser still provides some  optimisation opportunities as we say. The safety valves would be fine on a 3  inch scale engine and might just about serve for a 4 inch, but are much too  small for this size of boiler.\u003c\/p\u003e  \u003cp align=\"left\"\u003eLength 88 inches\u003cbr\u003e  Height 65 inches\u003cbr\u003e  Width 44 inches\u003cbr\u003e  Flywheel 20 inches diameter\u003cbr\u003e  Rear wheels 33 inch diameter\u003cbr\u003e  Front wheels 20 inch diameter\u003c\/p\u003e  \u003cp align=\"center\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019243999573,"sku":"3413","price":7750.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/3413-1.webp?v=1779903291","url":"https:\/\/stationroadsteam.com\/products\/6-inch-scale-allchin-traction-engine-stock-code-3413","provider":"Station Road Steam","version":"1.0","type":"link"}
