After scouring layout books, Lionel catalogs, and even this forum, this is the track plan I'm going with. However even though I found two nice images for this layout (the second one I attached below), I for the life of me can't seem to find a blueprint showing the dimensions of the curves and straights. Perhaps it doesn't matter, but let's suppose I estimate that I'll need a 10" straight track for a specific section, but I actually need a 9". It'll mess up the flow of the track. As for the curves, I can see what position the tracks would turn, but the images don't specify the degree of the curves, like is it a O-72, an O-48? I could just buy every single option available and test them out, however that would mean that the tracks I don't need would have to be stored and end up gathering dust, and that wouldn't be very efficient.
Essentially what I'm looking for is a blueprint which details the dimensions for each track I would need, or at least a list of all the necessary track types.
