Jeff Smith wrote:A single frequency by its very nature affects capacity; that's one less train of excess capacity. If you had read up-thread, the proposals are 6-10 peak hour trains, with 4 reverse peak, with two-off peak trains in each direction.For example (and I'm completely making up numbers), if a track has a capacity of 30 trains per hour with no station, or a capacity of 20 trains per hour assuming 5 trains per hour stop at the station, then if the track only sees a total of 15 trains per hour (10 that don't stop and 5 that stop), then the decrease in capacity from 30 tph to 20 tph is not enough to affect the service. In other words, you could run your 15 tph with a station or without a station and it wouldn't make a difference (assuming evenly spaced intervals, etc., etc., etc.).
How is that not going to affect capacity?
Lackawanna484 <cut> I'd doubt MetroNorth would operate into Penn Station. That would require additional staffing, tickets, mechanical support etc in another location. Although top leadership would like more interface between LIRR and MN, it's highly unlikely that MN crafts would willingly accept LIRR people working on MN equipment if it came to that. <cut>Mod Note: Quote from viewtopic.php?f=67&t=5943&start=15, and thread merged with PSAS thread.

LIRR third rail will be extended 1 mile to the 25 Hz/60 Hz phase break on the Hell Gate, and M8's (already compatible with LIRR over-running third rail) will make the power switch there. Very minor expense, as 1 mile is too short to require any new DC substations.F-Line,
