Well I don't know! I subscribe to 3 model magazines and I don't see 100% craftsman type layouts - 'tho that could be just me. I've seen photos (and models) that had me saying "wowser - that looks real!" Then other photos and models - "naw, mine looks more realistic!" It gets real subjective real fast. Back in the 60s/70s we had a kind of loose round robin of 5 to 7 modelers. The second guy I met was stationed here in the Navy. Now that guy was a "craftsman." His favorite kits were, as I remember, produced by a company called Cannonball Carshops. Those kits were absolutely state of the art back then, not easy to find but he did. And by the time we saw them, not only were they perfectly decaled - they had uncoupling levers! And if you remember the Varney F-3, it was at best a noisy beast. Not his set. They did make a soft purring noise while running in ACL's purple & silver scheme that made Mantua/Tyco's factory equivalent look not so good. Painted by guess who? But, his layout - the "Plywood Pacific" personified. A 4'x8' piece of plain 1/2" plywood. It did have 3 turnouts (which worked perfectly), rail, Kadees and ramps, and perfect electrical connections, i.e. nothing ever failed or malfunctioned in any way that I ever saw. For 3 years that was it! His polar opposite - well he had as I recall a lot of Penn-Line and Mantua r-t-r cars. He bought Penn-Line train sets in multiple, r-t-r you know. I still remember the 2 back to back work nights we spent converting all those Mantua cars to body-mount Kadees. Directed and helped by our resident craftsman. Now this gentlemen had a 20' x 24' foot space. Scenicked with plaster, twigs with globs of lichen attached and more dyed sawdust than you can imagine. His track, questionable in several locations. Block control - well it mostly worked. But he had done his best to lay it out as a real railroad. We could and did move trains and cars as close to prototype as we knew how. Guess which model railroad was hands-down our favorite to visit and "operate" on. Even our craftsman said "I may have built a perfect machine, but K---- has built a model railroad." So there again, a commonality of purpose, regardless of how achieved, seems a unifying purpose.
