At some point, the newer East route was added. It looks like I was successful in removing the incorrect NW and NE routes, but the Windows JOSM application is surprisingly buggy, so I don't know if or when I'll be able to add the new Express route or the other normal fixed routes (NW, NE, and S). If someone else can, I'd appreciate it. I'll continue to try when I am able to, just don't know if or when I'll be successful on that front.
