As we've pointed out before, it comes out as a seriously large engine in this gauge - 18 inches longer than a 3 1\/2 inch gauge Britannia and with 42 square inches of grate area (just less than a 7 1\/4 inch gauge Stafford!)\u003cp\u003e\u003c\/p\u003e\u003cp\u003e    This one has come to us from the family of the builder, a man who, now advancing in years, has had to give up model engineering after a long, productive career.\u003c\/p\u003e\u003cp\u003e    The son of a father who worked on the railways and a grandfather apprenticed at Stratford Works, this is the second \"Columbia\" he built, the first completed and subsequently sold many years ago.\u003c\/p\u003e\u003cp\u003e    The engine rolls freely and runs on air, with some fine tuning of the valve settings remaining to be done. The regulator requires finishing - it was removed for the hydraulic test.\u003c\/p\u003e\u003cp\u003e    The boiler has had a twice working pressure test off the frames with new certification issued.\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019242557781,"sku":"11540","price":2950.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/11540-1.webp?v=1779903273","url":"https:\/\/stationroadsteam.com\/products\/3-12-inch-gauge-baldwin-4-8-4-columbia-stock-code-11540","provider":"Station Road Steam","version":"1.0","type":"link"}
