As a Finn, I find the variety of foreign cultures to be quite interesting. Especially when it comes to model railroading. From what I can tell, Europe and USA are two very distinct worlds in this respect and never shall the two meet.
From what I can tell, European layouts are typically very small. I guess we have less and smaller garages and basements. Of course, Euro prototypes are smaller (shorter distances, shorter trains, shorter wheelbases), too, so there might not be a need for that 30" turn radius.
Another interesting thing are kits. There’s no such thing for Euro stuff. Our stuff is almost universally ready-to-roll. Many hobbyists’ve grown up on Märklin, and are quite used to “open box, place on track, turn knob” as being the standard installation procedure. the idea that one would have to spend 2 to N hours assembling, painting and weathering the thing before use would be preposterous to us.
My personal pet peeve are couplings, though. There are no European standards, de facto or otherwise. At present, there are at least three rival close coupling types commonly seen with the big manufacturers (Märklin, Roco and Fleischmann), that have roughly the same operating characteristics but are completely incompatible. On the flip side, at least there’s the saving grace of the NEM 362 quick-change universal coupling pocket.
Then there’s the Internet. To date, I’ve found only one decent-sized European model train forum, and even that was completely anaemic. Of course, since HO is nigh-unheard-of in UK, maybe I should look for one in Deutsch.
Just my two cents, feel free to chime in here if you’ve ever pondered the same topic, about the hobby which both unites and divides us.
