Weighing only four tons  in working order, with a three foot wheelbase, they could get round the tightest  corners on the grottiest, temporary track almost anywhere it could be laid.  Which, in turn, makes a 7 1\/4 inch gauge version just about ideal for a compact  garden railway!    \u003c\/p\u003e\u003cp\u003eThis is a well-made engine to Ken Swan's \"Wren\" design. Copper  silver soldered boiler fed by injector and crosshead pump. Outside cylinders  with slide valves actuated by Hackworth valve gear, mechanical lubricator.  Spring-loaded drain cocks, operated from cab.    \u003c\/p\u003e\u003cp\u003eThe engine steams quickly and runs very nicely. The motion work is in good  condition, the paintwork, although serviceable, could use a little attention  around the edges. Surprisingly powerful for its size, easy to drive and with the  robust, simple construction of the full-size prototype, it makes an ideal  beginner's engine.    \u003c\/p\u003e\u003cp\u003e\u003ca href=\"http:\/\/www.irsociety.co.uk\/Archives\/5+6\/KS_Wren.htm\" target=\"_blank\"\u003eThe  Industrial Railway Record have published an article giving much detailed  information about the class here.\u003c\/a\u003e    \u003c\/p\u003e\u003cp\u003eLength 40 inches\u003cbr\u003e  Weight approx 250 pounds    \u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ccenter\u003e\u003c\/center\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019094217045,"sku":"2306","price":5500.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/2306-1.webp?v=1779901791","url":"https:\/\/stationroadsteam.com\/products\/7-14-wren-stock-code-2306","provider":"Station Road Steam","version":"1.0","type":"link"}
