I need some info if someone has it, or a link to it, I'd appreciate some help. I need to know the prototypical rail dimensions in the US. Rail hight and width. If you have it for different applications such as mainline, siding, yard, branch lines and so forth that would be a blessing. I found something on tie dimensions, but not spacing, so that would help too, but it's not as important as rail dimensions. I've spent quite a bit if time searching the Internet and have come up dry each time, except I did find one site that had standard rail lengths, which I'm not that interested in, just hight and width. I've been using Google, maybe I should try a different search engine. Anyway, any help would be appreciated.
