I disagree that Inland Route improvements would benefit only travel within Massachusetts. I've ridden Inland Route trains and the Lake Shore now and then, but always for interstate travel, even when I lived in Boston. I live in Pennsylvania now, and I traveled to Pittsfield using the Lake Shore for one leg of the trip earlier this month, and from Pittsfield to Syracuse. I have family near Framingham, so I've ridden the Lake Shore to there. Faster, more frequent, more reliable trains on the Inland Route will benefit interstate travel.
The Biggest benefits are payed inside Massachusetts for the state’s infrastructure projects. I hold to that. Not only as that’s what’s getting the investment for work in phases but also as the way the Subdivisions we are talking about string and the Lakeshore limited brakes down.
Beyond Pittsfield you would be getting diminishing returns due to other conflicts and scheduling.
@Literalman you point to a Pittsfield to Syracuse NY city pair. Here the problem on getting that benefit. The Origin Pittsfield is at the end of the Massachusetts segment of line, The very next stop heading west is Albany Rensselaer NY and the transition from the Berkshire Subdivision to the Empire corridor. Assuming everything has gone to plan the train arrives on schedule from PIT to ALB. (currently the delay is often on the 449 from Boston due to the single line but we are talking after the improvements)
The next leg isn’t guaranteed to do the same.
Because the Lakeshore limited 449 has to merge with its sibling Lakeshore limited 49. To form the Lakeshore unlimited mega zord…
I mean to form the Westbound Lakeshore limited with your stop in Syracuse on its way to Chicago.
The question is whether that Combination train is also getting an expanded schedule? And if so how far? Buffalo? Chicago?
Is there the demand for that? How much? And then the visa Versa. If you do the Full Lakeshore limited but it gets delayed which which can and does happen often badly. What happens to the potential commuters?
As usual some posters only think of the end point. Meridian, Hartford, Windson, Springfield, Palmer, Worcester, Fareham, & others will all benefit for inland route service. Start the service now with 1st departure at 0600 SPG and maybe one at 0730. then stasrt improvements to quickly get to 2 hours SPG <> BOS and eventually 1-1/2 hours. Have one leave BOS 0600 - 0630 going thru to New Haven with important stops at Hartford,
Lakeshore limited 448 and 449 service expansion on its own has a huge benefit impact inside the ALB to BOS area.
Beyond the MBTA bubble on Boston Metropolitan area passenger rail seems to vanish at Worcester.
Until Springfield where it picks up limited north bound along the Connecticut River line and plentiful Southbound via Amtrak and CTRail via the Harford Line though New Haven.
Pittsfield has some independent NYC access via Albany in the Summer months but very limited. And almost No service to Albany other than the Lakeshore limited the rest of the year.
What this starts to do is basically establish the first steps to a true regional rail system inside the Bay state from end to end.
Via the Hartford line yes you would see increased access to passenger south and north. As more
Travelers have options however I suspect it’s not enough to create a true alternative to the Shoreline route of access from Boston to NYC or Visa Versa.
The Hartford line has potential, but also it has a few Choke points. It’s partially double tracked but Hartford Union Station and the I84/I91 funnel it to single track. Hartford Union is served today by a single elevated platform the old second platform was removed due to age and cost cutting in the 90s. With highway viaducts and development that took place in the 20th century the Station is caged in. For the last decade+ Harford and the State of Connecticut have been arguing around what to do. An Inland route is laced right in the middle of that. They were supposed to have figured out a plan in 2019 for their version of the big dig but it’s still an mystery. A true Inland route that could hypothetically bypass the Bottlenecks of Eastern Connecticut railway I believe can’t be done without modernization of Hartford’s railroad station. Unless you intend to bypass it.
