As I have post in the past....I have been on a quest to replace my Traditional size trains with scale items.
I know MTH is easy......20 vs 30......and I know Weaver, 3rd Rail, Williams brass and others are scale.
But I can't tell if a Lionel loco is scale or not???? I know Lionmaster is semi-scale and starter sets for the most are semi-scale. But looking at a Lionel Mike I coud not find if it was scale or not.....seller said 'Yes...it's O scale'....no help. Is there a method like MTH has??? Thx
