So, I was doing a bit of digging out of boredom, and have discovered a rather interesting fact. In the 50's and 60's, There was actually O gauge set produced in the soviet union, described as having a diesel-type locomotive, two freight cars, two passenger cars, 3 street lamps, 3 signals, 3 operating accessories, and various other things used to operate the set, such as transformer and track. The first locomotives in the 50's, labeled "Stalin-era", had Stalin's initials engraved on the sides of the engine, while later engines did not, and were labeled "Khrushchev-era" locomotives. They were produced for 19 years, production ending in 1969. They were made in a variety of colors, and there are rumors going around the current Russian government considers them "National Treasures", and will forcefully apprehend anyone trying to take them out of the country! I know of at least one set here in america, and am going to see if I can negotiate a deal to get my hands on it. (Imagine owning a national treasure!) Here is a photo I have found online of the set, an artists illustration
Interesting seeing girls in the picture, model trains were normally considered a boy's toy.
If memory serves me correctly, there was also a model train made in the soviet union in the 20's or 30's, though I don't have the energy to search for it for a second time.
