What gauge is the Tomy line?

[Super]

I find that scale isn't exactly defined here. I think HO people are a match for Tomy trains as far as scale are concerned but I find a lot of HO buildings are too small to the eye in the layout next to the Tomy trains. I also find some of the S and O scale buildings look good but a lot are just too big. If you are using Plakids, they are not to scale with these trains and are probably closer to O scale. So Plakids do not fit with HO buildings but do work with S and O buildings. Same goes with accessories, trees, luggage etc. I find that some HO accessories fit nicely with the trains but are too small for plakids. Our layout has a mixture of HO, S and O scale items. I don't think many of the Tomy or Trackmaster buildings are to scale with the trains. Now when you add in the cars and vehicles I don't think any of the Hotwheels, Tomica or Matchbox are scaled to the trains at least not as my eye sees it. I find it interesting to find buildings and/or accessories that aren't always for train sets but are sold with other toys or merchandise that, when placed in a layout just looks good. After all, isn't that one of the attractions to these models? That you aren't regimented to a scale like the serious model railroaders are to scale. Heck, even from one Tomy engine to the next is not to scale with each other.
