I think most Marx tin buildings are about standard or G scale. Some are even larger. But on a tin or "traditional" post war layout, I think most look cool enough to "pass".
The figures are usually a smaller scale, but they varied too. And many plastic structures had smaller doors than Plastiville (if I remember right).
I like the perimeter fence for the tin Alamo set & think it could be worked in easier than the rest of the set. Maybe even bashed to make a building as its lower than the short building's roofs If I remember right.
I recently passed over some Marx old west buildings in plastic. I passed mainly due to lack of space, but if the size would have been spot on I would have bought them & saved them. (The plastic was in "day glow" MPC-ish colors, so I'll likely paint them.)
I pulled up a dead spur on the shelf layout recently, and so I think I'm going back to get them. Plastic but only a few bucks each. Should have just bought them. Instead, I picked up the plastic lunar surface from the Marx Moon-base set to use with my Marvin The Martian themed "rocket train". (size=half of a 29" dia circle, about 7" tall)
I have, and use some of the toys from "Grandpas toy box"( a box of less than perfect toys, not suitable for him add to the train collection) I have oxen, ducks, dogs, cow, sheep, horses, African warrior, native American warriors and squaws, cowboys, and some "world culture figures" (people in very traditional ethnic garbs.
1:32(?) hard plastic army toys, and various other(smaller) plastic, and metal vehicles alike.
I've had a white plastic figure in a sandblasting hood working on a loco for many years now (40?). I thought he came from a figure set of an automobile racing pit-stop crew. But, it turns out he is a figure from that moon-base set, and its a chemical fire/space suit for putting out launch pad fires!
