In one respect, Rob, I’d caution against your choice of a European theme. Why? Simply because foreign layouts have never been well received by British Modellers. Indeed, the Continental Modeller probably sold in nth quantities compared to Railway Modeller for this reason, and sections for modellers of overseas layouts on British fora like RMWeb are very much ‘niche’.
That said, despite MRJ being overwhelmingly British railway themed, (apart from ‘Hurley’) John Wright’s wonderful Pennsylvanian themed layout of several years ago is a stand out for me, a key which unlocked the door to the dark side. I was simply fascinated, for instance, by the former Santa Fe’s lines as they wended their way through the dusty backstreets of Downtown LA, with their rusty rails sandwiched between industrial buildings seemingly left over from some mid Western town, a la Wayne and Eastwood,with barely a sleeper in site. I was hooked.
Additionally, I note that a couple of Columbian/Peruvian (?) based layouts by the same builder have been met with much acclaim of late, and requested to exhibit, so perhaps the tide is turning?
In any case, with your excellent skill set and attention to detail, I’m sure your creation will be well received, whatever the period/setting.
I’d say an unreserved ‘yes’ just by the appearance of those wonderful little tank engines with their multitude of valve gear.
Just my pennarth worth.
