The original engines were very compact, weighing only 3  tons. Of the twenty originally  built, 6 survive in preservation. The distinctive diagonal boiler was intended  to prevent low water level damaging the firebox when in less than skilled hands.  By the time the firebox crown was exposed, there can only have been about a pint  of water in the engine - as a further belt and braces measure, the full size  engines had a firebox that could be unbolted from the rest of the boiler for  quick replacement!\u003c\/p\u003e  \u003cp\u003eThis engine has been nicely made, little used and runs well on air. The steel boiler has  brazed in tubes, feed is by eccentric-driven pump from the second shaft. There  would normally be an injector fitted - the boiler has a clack valve for it on  the nearside, but no plumbing.\u003c\/p\u003e  \u003cp\u003eThe single cylinder engine has a slide valve actuated by Stephenson's  reversing gear - the flywheel is between the hornplates, along with the single  speed road gear and differential. The cylinder block is fitted with drain cocks  but no linkage back to the footplate.\u003c\/p\u003e  \u003cp\u003eA smart looking engine, well painted and (rather unusually in a model)  sporting the correct corrugated tin canopy as fitted to the original engines.\u003c\/p\u003e  \u003cp\u003eDrawings and castings for this engine are still available from Stuart Models.\u003c\/p\u003e  \u003cp\u003eLength 35 inches\u003cbr\u003e  Height 24 inches\u003cbr\u003e  Weight approx 150 pounds\u003c\/p\u003e  \u003ccenter\u003e  \u003ctable border=\"0\" cellpadding=\"0\" cellspacing=\"2\" width=\"200\"\u003e  \u003ctr\u003e   \u003ctd width=\"200\" align=\"center\"\u003epage 1 of 2\u003c\/td\u003e   \u003ctd width=\"80\" align=\"center\"\u003e\u003ca href=\"index_2.htm\"\u003e\u003cimg src=\"images\/next.gif\" height=\"30\" width=\"30\" border=\"0\" alt=\"Next\"\u003e\u003c\/a\u003e\u003c\/td\u003e  \u003c\/tr\u003e      \u003ccenter\u003e\u003ctable cellspacing=\"10\" cellpadding=\"0\" border=\"0\"\u003e    \u003ctr\u003e    \u003ctd align=\"center\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/center\u003e\n\u003c\/table\u003e\n\u003c\/center\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54009987858773,"sku":"2233","price":2100.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/2233-1_b336f776-d3b7-4ae7-81e2-d061a2f71d27.webp?v=1779899843","url":"https:\/\/stationroadsteam.com\/products\/3-inch-scale-wallis-steevens-simplicity-roller-stock-code-2233","provider":"Station Road Steam","version":"1.0","type":"link"}
