Strangely enough I had ordered a resin kit for Upnor Castle and between placing the order and it arriving in the post the Fairlie was revealed. Complete revision of my plans ensued - new layout design in progress.
In days gone by, I might have tried to envision a reality where a Double Fairlie worked heavy coal trains over the Mendips, but those days have passed, now, so I'm more interested in those purchased by the Midland Railway for use in the Bristol area.
