Modelled to represent one of the ten locomotives built as a sub-class in 1955, with experimental Franco-Crosti boilers, a design featuring a pre-heater drum mounted beneath the main boiler. Flue gases were directed from the smokebox back through secondary flues in the pre-heater, emerging from a single, side-mounted chimney.\u003c\/p\u003e\n\u003cp\u003eLoading gauge considerations meant that the standard 9F boiler had to be reduced in diameter to allow room for the pre-heater beneath - the resulting loss of heating area causing the engine to be de-rated to 8F.\u003c\/p\u003e\n\u003cp\u003eThe boiler had had a twice working pressure hydraulic test, the chassis runs on air. It's fair to say that steaming it is something of an acquired art...\u003c\/p\u003e\n\u003cp\u003eRarely modelled - we've only seen one other, that in 5 inch gauge - this is a well made, detailed representation of a well known experimental class. It needs a new owner with an interest in the design, and the experience to get the best from it; we see the model, like the full-size prototype, as something of a development project.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54373758271829,"sku":"13379","price":5950.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/IMG_8256.webp?v=1784031826","url":"https:\/\/stationroadsteam.com\/products\/3-1-2-gauge-br-9f-2-10-0-stock-code-13379","provider":"Station Road Steam","version":"1.0","type":"link"}
