So is this the thread where we discuss Northern Tier stuff?
I was thinking about this... as best as I can tell, the
Northern Tier proposal calls for only four stations:
- Boston
- Fitchburg
- Greenfield
- North Adams
Of these, only North Adams receives unique service, and of course Boston and Fitchburg are already spoken for. The current proposal outlines a lower-investment and a higher-investment alternative:
Those are some pretty hefty time savings, at what looks like a pretty hefty upgrade cost. About a half hour saved between Greenfield and North Adams, and another half hour saved between Greenfield and Fitchburg.
But why not run the service via Springfield instead?
The NNEIRI estimated BOS <> SPG travel times at about 2 hours (give or take, depending on which alternative you look at). It then estimates 45 minutes from Springfield to Greenfield -- putting it on par with the 2h35m estimated in the Northern Tier's lower investment alt.
If the higher investment upgrades between Greenfield and North Adams are incorporated, in theory you could get a North Adams <> Springfield <> Boston travel time of about 3h30m. That is admittedly slower than the even 3h afforded by upgrading all the track between Fitchburg and Greenfield, but it would be achievable with a fraction of the cost (given its ability to leverage East-West Rail and Valley Flyer infrastructure improvements).
Plus, routing through Springfield would give North Adams one-seat connectivity to Springfield and the Connecticut River Valley (including Northampton and Holyoke), as well as Worcester (which I'd argue has a heavier pull than Fitchburg), and will offer much more frequent transfers to CT and NYC service at Springfield than will be available at Greenfield.
In addition, even if we went with the lower-investment alternative (1h20m between Greenfield and North Adams), you
still end up with Boston <> North Adams travel times of just about 4 hours -- but with the added connectivity benefits described above.
Routing via Springfield would allow Northern Tier service to be woven into the larger East-West Rail megaproject, instead of having to stand alone and advocate for what otherwise looks like a rather boutique service. Rail to North Adams will require upgrades to trackage between the Pioneer Valley and the edge of MBTA territory; going via Springfield gives you more bang for the buck, and makes monies available for higher-impact upgrades between Greenfield and North Adams.
