To some extent this argument is a bit of water under the bridge since PennDOT and NS have already struck a deal to spend something like $200 Million to add trackage and universal crossovers at various places as precondition for adding a second train. Allegedly adding a third train should not require any further work, but then a new management team at NS inevitably could think otherwise, since the whole thing is somewhat capricious IMHO. But at least there is a somewhat more activist STB overseeing this process now.
I mean, I don't see a problem with effectively giving them another $50-100m for another frequency since you're essentially "buying" a slot for a train that doesn't behave like a freight train (it runs faster and makes multiple intermediate stops, so it basically takes slots from a few freight trains - even if the capacity isn't needed
now, it still represents a loss to potential future operations).
[I concur with the suggestions on here that an overnight train on this run would make sense for that third train. You don't even need to slow it down
that much...a extra 30-60 minutes should keep HAR and PGH out of the 0000-0600 "trouble spot". In ideal circumstances,
that could be extended further west to Cleveland, Detroit, Chicago, or somewhere else.]
I'll edit to add: If you're willing to sacrifice HAR (a debatable decision, to be sure, but potentially still workable), you could fiddle with the schedule to get a quasi-commuter timing into PGH (arriving around 0800-0830). Trying to execute on a reversed schedule (leaving around 1700 or so) would also work if you're willing to sandbag NYP - the main question would be if you could squeeze
just enough time out of the timetable to get into PHL by 0000 (though that's one case where I might just say "screw it" and rip all of the padding out on the way into PHL so I can timetable that...0000 is one of those times I don't think OTP is super-important.
I'm as big a proponent of rail as anyone, I think, but with the caveat that it needs to be practical. I just don't believe Pittsburgh has the population density in suburban areas to justify the heavy investment that heavy commuter rail requires. Add to that, the pandemic has sapped downtown with many companies still doing mostly remote work. Even the long dreamed of prospect of light rail to Pittsburgh Airport isn't likely to ever happen. The airport bus service from downtown to PIT, subsidized by the Airport Authority, is poorly patronized.
I agree with you on the issues with downtown jobs being hit on a permanent basis. That being said, commuter rail can be (relatively) inexpensive by comparison, particularly with a pliable host railroad and particularly vs light rail and so on.
I think that’s a good idea. My only concern would be timekeeping. I’d also really like through cars to the Capitol (even though within a few years the Capitol would end up being the stub train.)
So, I'm not convinced of this because of the nature of the Capitol Limited. The Pennsylvanian (on its current timetable) misses the SB Silver Star. It has less than an hour for the connection to the SB Crescent. NB, it misses both as well. The Meteor is a good connection with it on the present timetable (though that could plausibly be rendered spotty at PHL if timekeeping became "touchy"). Simply put, the Cap's main role is in providing Midwest-to-Southeast connections (IIRC CHI-WAS is like 40% of the Cap's ridership, and another 20% is CHI-PGH or PGH-WAS), and unless you can replace that on a daily basis it'll remain as-is.
