The 2-10-0 Decapod went to Russia and the rest mostly went to the PRR railroad, but trains weren't limited to Europe. why not a American train dio, if not for the railroad here the US would not have been in the war as the railroad moved all goods, troops, armor..... Why not a 0-6-0 pulling a flat of Sherman's, or P47's and why not a 1/35 Liberty ship being loaded.
Hi, All! The New York, Susquehanna and Western also bought a few of the 2-10-0 Decapods. NOTHING larger than a 2-8-2 was ever shipped to England or to Western Europe. Anything bigger than a US-built Mike was just WAAAYYY TOO HEAVY for the light European tracks to support, WAAAYYY TOO BIG to negotiate the tighter curves, and just a bit too tall for European tunnel and bridge clearance heights. As to comparative size, "big" German BR-52 2-10-0s weren't much bigger than an average American 2-8-2...
When comparing my HO LILIPUT Reichsbahn BR04 4-6-4 to one of my BROADWAY LTD NYC 4-6-4 Hudsons, the American locomotive, even with it's typical NYC "Racehorse Look", (Long, low, and perfectly proportioned.) is a larger, more robust piece of machinery.
Just a bit of WWII trivia: When our WWII GIs first arrived in England, Scotland and Ireland, they thought the English steam locomotives and trains were just big toys. They especially thought the European whistles were hilarious- "They go PEEP!", nothing like our American steamers' whistles BLASTING your face off if you got closer than a hundred feet away... No insult intended towards our British and European friends- Personally, the German Reichsbahn BR04 4-6-4 and the British Southern Rwy's A-Class Gresley 4-6-2 Pacifics are two of my favorite European Steamers!
My favorite American locomotive? Hands down, the New York Central J-series 4-6-4 Hudsons, both in the standard and the streamlined 20th Century Limited Dreyfuss configurations. That BROADWAY LIMITED J3a streamlined "Super Hudson" of mine is GORGEOUS!!!
Forget about 2-8-4 Berks, 4-8-2 Mountains or any of the REALLY big American Articulateds ever showing up in Europe. Besides, to turn a UP 4-8-8-4 Big Boy around would require a greater land mass than the whole country of Lichtenstein!!!
But can you imagine a Big Boy in 1/35 scale?!? =:O
