Larry, I think he meant the actual dimensions and dirverging route radius of the Kato switches compared to other N gauge switches. Casey, not being in N guage, my suggestion would be to get the eaxt dimensions of the Kato switch and then write to other manufacturers about the dimensions of their switches. I suspect that there's no other switch with the exact same dimensions and, unless you have some really good reason, you're much better off sticking with one brand of switches. I have several different brand on my HO layout and it was troublesome getting them all to fit together.
