Yeah, post Christie Street Connection, the branching is pretty wild. Nice for having some good options that minimize transfers, but I have to imagine it's hell

Yeah, post Christie Street Connection, the branching is pretty wild. Nice for having some good options that minimize transfers, but I have to imagine it's hell for scheduling. The C shares track with the B in Upper Manhattan, the E in Midtown and most of Lower Manhattan, and the A from Lower Manhattan through Downtown Brooklyn until finally getting its own track. Going by common tracks, the A, B, C, D, E, F, G, J, M, N, R, Q, W and Z have to be considered correlated. So that's basically the whole IND+BMT, except for the L!
