layout where do we talk about layout i was curious about curve terminology i e the fact that a two degree curve is sharper than a one degree curve and where the degrees are actually measured and what the relationship is to radius i found the answer easily enough with a google search but it clearly ought to be discussed in wikipedia somewhere along with other details of railway surveying it's somewhat amusing that we've got a whole article on track transition curve but no coverage of normal curves at all that i can find does a layout or surveying section in this article make sense i might just get bold and start adding it
