I'm wondering what "scale" the N gauge Thomas range is adhering to, since N gauge in Europe and the USA is proportioned at 1:160, in Japan it is 1:150, and England it is 1:148, and it's predecessor (called OOO or "treble O") was 1:152. While the Thomas range is pretty much fantasy, this "scale" question relates to the general size and proportion. The Japanese "Thomas" Models, supposedly at 1:150 proportions, seem noticeably larger when compared to American N gauge models, how do the new Bachmann N models stack up in comparison?
