6 Av Express ?
6 Av Local ?
You can cut the to Chambers, and the to begin with is what I would say. I know they had the Brighton Express, and the Brighton Local, but this is different. There are only 2 Local stops on 6 Av, and I don't think that it can handle that many trains. And plus at one point you will have the and on the Local track, with the crossing onto the 8 Av Local.
