That's interesting! I ride the E train every day that I commute into the city (half of the weak), and I'm pretty sure that even at peak times, in Manhattan, it's more than 4-minute spacing. I once lived by the F train, and it's hard to believe that it ran enough trains to make up for that. So 30TPH seems wistful, indeed!
The 4/5 actually seems to achieve 3-minute spacing consistently, though.
- bobthepanda 8y agoIt's a lot more noticeable in Queens; trains roughly do show up every two minutes. The major issue is that all the merging and interlining of services introduces many conflict points; most subway systems try to limit the branching of services on any given track pair, and very few have reverse-branching, the combination of branches into trunks in the outer parts of the system (like the E/F, the 2/5, the A/B/C/D, the B/Q, the D/N, etc.)
- acjohnson55 8y agoYeah, 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!
