i just want to know, how can i modify a route without having the route being messed up. I tried Making the a run local in brooklyn via the c coding and it resulted in misplaced objects, like a small part of the local tunnel after hoyt schemehorn is gone and it surfaces at lafyette avenue, and again with the tunnels that the C uses after euclid avenue
the only successful route that ive managed to mod was the old K line, making it go express in both new jersey and brooklyn
if anyone would help me because i would like to keep these files to myself
