Widely-regarded as the first close-to-scale drawings produced for  a model traction engine, Hughes had access to the full-size engine in the 1950s  (an engine now in preservation) and produced a highly detailed design which  remains extremely faithful to the original. Written up in the \"Model  Engineer\", Hughes subsequently published the construction articles as a  book which is still available.\u003c\/p\u003e  \u003cp\u003eAlthough often tackled by newcomers to model engineering attracted by its  modest size, the design calls for a considerable amount of experience to build  successfully, both in the ability to tackle complex individual parts and also to  cope with the sheer quantity of bits - basically if it was on the original  engine, it appears on the model.\u003c\/p\u003e  \u003cp\u003eCopper boiler, feed by mechanical pump on the second shaft and injector.  Three cock water gauge with blowdown, pressure gauge. Two speed with  differential and back axle-mounted winch. Mechanical lubricator for cylinder  with drain cocks operated from footplate.\u003c\/p\u003e  \u003cp\u003eThe trailer is a well thought out and nicely executed job in its own right.  It has a set of ramps allowing the engine to be loaded onto the back for  transport - a quickly detachable long handle makes pulling and steering easy.  With the engine off the trailer, the long handle is removed and a tow-bar fitted  allowing the engine to pull its own trailer.\u003c\/p\u003e  \u003cp\u003eThe engine was built many years ago and has never been steamed, although it  has been run on air. The governor requires work to complete and the mechanical  lubricator lid is missing.\u003c\/p\u003e  \u003cp\u003eLength 26 inches\u003cbr\u003e  Weight 80 pounds\u003c\/p\u003e  \u003cp align=\"left\"\u003e\u003c\/p\u003e  \u003cp align=\"center\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019775267157,"sku":"2552","price":2950.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/2552-1.webp?v=1779907030","url":"https:\/\/stationroadsteam.com\/products\/1-12-inch-scale-allchin-traction-engine-stock-code-2552","provider":"Station Road Steam","version":"1.0","type":"link"}
