I agree that the Keystone Service is like its own commuter service. First, there are many people who live in the more rural parts along the route who commute to jobs in Philadelphia and probably even Harrisburg. As for the future with 125 mph operation on the Keystone Corridor, there is a proposal to have the travel times reduced to a little less than three hours from New York Penn Station to Harrisburg. I would love to see that happen and it would benefit the Pennsylvanians.

Assuming that the Pennsylvanian trains get Chargers, PHL-HBG will be one of the few places in the country that they can max out.

The big hurdles I see are mostly from PHL - PAO. The curve between Overbrook and Merion is brutally slow. Not sure much can even be done.

I presume moving the interlocking out of the curve at Overbrook would help.

Yes, there is little that can be done to raise speeds between PHI and PAO. Maybe the speeds can be raised between 30th St and Overbrook but probably not by much and then the speeds would have to be the same between Overbrook and Wynnewood probably. There are very sharp curves between those stations. It looks like west of Wynnewood, the curves aren’t as extreme in many spots. It’s probably better to keep Wynnewood to Paoli at a top speed of 80 mph.

The curve between Merion and Narberth is 60/65/65/60.

The curve at St. Davids is 60 on all four tracks
The curve at Berwyn is 50 on all four tracks

I just remembered that in Berwyn, there is a bit of a sharp curve east of the station. The real speed increases would have to be done west of Paoli.

This is, if I recall correctly, where the current higher-speed rail starts.

West of there, Gap curve always required a significant slowing, as did another curve whose name I forget; fixing either of them is probably not economic.

Recall that the stillborn high speed Metroliner service to Harrisburg in the late 1960s was supposed to be a SEPTA
service and that even Silverliner II and IIIs were regularly used in single car Harrisburg locals during the 1970s.

At 104 miles, the Keystone is shorter than Manhattan to Montauk, just nine miles more than the Port Jervis
Line and 18 longer than the Hiawatha.

There are two turns. One in Gap then the other in Atglen where the Low Grade came into the Main Line.

Was at Levittown today and noted not one, but three Keystone trains with bookending Sprinters. Is something wrong with the Metroliners?

Ether that or they have enough Sprinters that they can book-end and save some time on engine swaps.

...scratch that, I'm wrong. Keystone doesn't go past Harrisburg, line's electrified. Wrong thread for that?
