Having purchased a copy the article within has ideas based on Dungeness, Cleethorpes (Lakeside) and a room-filling Fairbourne. As is usual with Paul's plans, the presentation of them is well thought through with an equal dose of compromise and practicality.
Looking closely at the plans there are a few pieces of artistic license, but that is typical of many plans published in the mainstream press, with track spacing, turnout length and curve radii the usual suspects.
Naturally I am quite taken with the Cleethorpes plan, despite it being a solid 8' x 3' lump. It could certainly be made to work, I recall making a plan for this part of the railway (in terminus form) myself in a length only slightly shorter.
One of my contacts did make the comment that no attempt is made to identify what locomotives or rolling stock could be used, maybe in part 2 we shall get some suggestions, though based on previous content in the magazine I suspect we may see a Farish diesel with a hole cut in the roof at some point.
I was only observing to someone at the Hull Summer Show last weekend that it was probably easier now to recreate a miniature railway in O9 now than ever before. Take your pick of quality N gauge steam loco, open up a driver's seat in the tender and build up some of Roger Chiver's plastic coach kits...
