That explains a lot. I just read the "G-Scale" page on Wikipedia and they explain a lot of how the different manufactures created the different scales but all used the same size track.
This is actually quite interesting for me.
I'm building an outdoor "G-scale" model railroad. And I actually think of the G as referring to "Garden Trains", since I'm basically building this around my landscaping gardens in my front yard.
In any case, I actually decided early on to build all my buildings, cars, and people using 1:32 scale models. I wanted to stick with a single scale for the main scenery and dioramas. I chose 1:32 scale for several reasons, one of which is because it will allow me to do what I want to do within the space of my gardens. A larger scale like say 1:24 would be a bit large for the area I have to work with.
My current trains are Bachman "Big Haulers" which are indeed 1:22.5 scale. But I'm hoping to eventually replace these trains with my own home-built trains. And I would actually like to build my trains in 1:32 scale to better match my dioramas.
Apparently I'll be able to do that and retain the same size track the whole way through. That's makes it really nice.
In the meantime I'll need to build this covered bridge large enough to accommodate my 1:22.5 trains.
If I put any up for sale I'll just say that they are 1:22.5 scale, and call out the actual dimensions. That way I won't need to worry about calling them "G-scale".
