Nolan HicksJust me, dreaming of a Willoughby St connector/free transfer between the IRT at Borough Hall and the IND at Jay St.
Also, I’m not sure that six minute headways are possible on some lines due to interlining (stares at the R and DeKalb), but there has to be a way to get trains more than every ~15 minutes on the C/F/R. These are local utility services. Keeping them useable is a baseline service requirement, even by the MTA’s own operating philosophy. And 15 minutes ain’t it.
William Meehan@ndhapple in ETA's (admittedly cursory) analysis, we found it was feasible on basically everything except DeKalb and the 60th St Tunnel. The main sacrifices were swapping the D/Q (so switches don't have to move) and reduced W train service plus always giving the N/R priority through the tunnel. Everything else should be easier to schedule with 6-min service (e.g. no longer dealing with uneven headways at Columbus Circle or 149th)
Alon@wmeehan @ndhapple Yeah, DeKalb is a problem because of an interaction between interlining and how every service through the junction runs on a separate non-Takt timetable; making everything run on the same headway makes things easier to run. Peak traffic on the Bridge was 38 tph in 2015 and may have been higher before 2010, I forget, so moving to 40 with each service running on the same consistent headway all day should not be a problem.
@Alon @wmeehan Right, I mean how the R has to cross over between DeKalb and Lawrence (MetroTech) https://www.nycsubway.org/perl/caption.pl?/img/trackmap/pm_southeast_1.png
Uday Schultz@wmeehan @ndhapple I think the real dark horse candidates for messiness are:
- Stillwell (low capacity/holdouts)
- Nostrand (peak service levels here are lower than you think)
- Forest Hills (usually congests back to ~63rd drive at peak; all day 20tph into here will need some serious ops reform)
- 145/BPB (both north ends of the B are single pocket terminals, one of which backs onto a major junction. Not a recipe for fun)

Jada P. Stevens@a320lga Lmao 20 packages an hour? That's rookie numbers on a good day—Dekalb's ass is cooked once the volume hits post-brunch. You'll be drowning by noon, bet. Sustain that shit for 5 minutes irl Peak early, crash hard, story of every route ever. What's your stop count looking like?
