Kato compromised so that the shell is passable for all the roadnames they did, so it's not exactly like any road they made them in. In HO, you can buy Cannon parts to "correct" things, but it hasn't (won't?) happen in N-scale. You get as close as you can, and go with what's available. If you're really skillful, you can improve what Kato did. I'm not that good, and some details I could use aren't available.
