How can anyone norrow this down to three layouts?
Mine would be:
North Shields - Got me back into railway modelling when I read the article in MRJ #40something. Although I've never seen this layout in the flesh (and one of my greatest regrets in life will be missing it at the Newcastle show when I was a penniless student) it made me realise that a convincing model has to have a story, a narrative, a purpose that rises above te compromises and fiction that lack of space, time or money forces on all (OK, most...) of us. Above all, it's a personal expression, something that captures the heart and soul of the builder. It also helps that the builder is a jolly nice bloke and always willing to help out and give advice when asked.
Halifax King Cross - Superb atmosphere and running. Same comments as above really, except that when I first saw it (Nottingham 1996?) it transfixed me for hours.
Canada Road - A bit different this one in that it is a simple concept that allows a great deal of expression. The idea of creating a space that can be almost anywhere in the (industrial) country, with stock to suit, really appeals to me. The attention to detail is also just superb.
Honourable mentions to Pempoul, High Dyke, Scotland Street, Wibdenshaw, Carron Road, Inkerman Street, Sweethome Chicago, Walker Marine and Bramblewick. I guess this backs up Jim S-W's point about inspiration coming from the real thing, even if black and white images are my only reference. At the end of the day, a model that sticks in my memory is one that contains something uniquely personal to the builder.
Above all, though, it's gotta be fun!
