Compared with the Central Mass being abandoned, it already carries CSX locals and has the capability to connect to the Pike, Route 20, Route 9, and 495. IIRC this was studied a little while back and it came out much more favorably than the Central Mass. Additionally, you'd be funneling trains onto the Worcester Line, which is already in better shape than the Fitchburg although they may be more equal after the upgrade program. There's still capacity for at least one additional track from Framingham to Riverside (the ROW is four tracks wide with some platform encroachment), though the Pike extension bottlenecks capacity inbound from there. Honestly, I'd rather give the Central Mass to the rail-trail folks lest they try to rip up something more useful. Given that Weston is still unhappy about a gravel bike path, I doubt you will ever see them allowing a train through there again.
There was an I-290/Northborough commuter rail study done in 2002 by Boston MPO. It's never been archived anywhere, though. The now-outdated 2003 Program for Mass Transportation by the MPO has a bit summarizing it, though for absurd reasons they listed downtown Leominster instead of Northborough as a terminus (there is a city bus that stops in front of the old NYNH&H station and drops you in front of North Leominster on the Fitchburg Line nearly walking distance away). From the PMT report it shows $375M (2003 dollars) capital cost for construction Framingham-Leominster with 7 stations that included park-and-rides at Mass Pike (Framingham), I-495 (Marlborough), I-290 (Northborough), and I-190 (Sterling) and restoring the railbanked (non-abandoned) Fitchburg Line connection to use East Fitchburg as the layover yard. There's not a lot to conclude from that little blurb because it's the extra running miles past 290 that send the cost-per-rider and operating cost spiraling out of control (16 mi. Framingham-290, 17 mi. 290-Leominster, 4 mi. to reinstate the severed Fitchburg Line connection). I bet three-quarters of the ridership is at that murderer's row of park-and-rides out to 290 + the likely Framingham Ctr. stop right in front of Framingham State U. Wasted effort to go any further than that. And the line's too curvy to attain tolerable end-to-end travel times, so keeping it a taut 16-mile scoop-up of park-and-riders extended off an otherwise conventional Framingham short-turn on the Worcester Line is where this extension hits paydirt.
I'd love to see the 2002 full-detail study at what the costs break down to. There's no question they'd all be high-ridership stops in terms of daily boardings. The economics hinge more on whether there's any off-peak demand whatsoever given how extremely skewed the station siting would be--excepting Framingham State U. and maybe the Bose and Staples HQ's by the Mass Pike--towards park-and-riders who are only likely to opt for this line at hours of peakmost highway congestion vs. driving a little extra to a Worcester Line park-and-ride all other hours and getting higher train frequencies. Someday it'll be necessary to do this...I'm just not sure 290/495/Pike are quite bad enough today in that region for this extension to break the out of the depths of the third tier for desireable commuter rail projects. And that's still one good tier higher than the Central Mass.
The Central Mass restoration makes a little bit more sense as a future follow-on to Fitchburg Secondary commuter rail. Leominster is forever kind of useless because of the Fitchburg Line proximity, increasing FL service, and a well-established local bus system facilitating better feeder service to the FL. But Berlin and Clinton are still in the transit cavity, and Clinton has an out-of-service track connection with the PAR Worcester Branch (southbound direction only) facilitating future run-thru options. So let's say Northborough gets a final +1 extension some years later to downtown Clinton with maybe a tiny intermediate stop at Route 62 in Berlin.
Now say some years after that the need becomes acute for Worcester reverse-commutes and firewalling Greater Worcester with more radial park-and-ride relief. The Worcester Branch heading out to the immediate north of the city starts having attractive uses...but nothing all that attractive to hook it to because Boston-Ayer-Worcester is a batty out-of-the-way routing. Boston-Framingham-Clinton-Worcester is not so out-of-the-way, but is geometrically so slow no matter how perfect the track gets upgraded that it can never be done on a plausible schedule. And maybe the routing isn't batty, but it starts to get murky somewhere around Clinton where the Boston park-and-riders end and the Worcester reverse commuters begin, leaving the mission statement of such a time-consuming thru run a little unclear. BUT...a Central Mass schedule on arrow-straight Class 4 track that swiftly makes all its native stops to Berlin/495 is much more appropriate for running thru to Clinton on the Fitchburg Sec., then turning south on the Worcester Branch and hitting Worcester Union station. 54 miles Worcester Union to North Station, same as the Fitchburg Line after the Wachusett extension opens, and only 10 miles longer to Worcester than the current Worcester line while serving entirely unique east-west areas. The change to north-south orientation around Clinton isn't severe enough to distort the ridership audience like any other routing would...it's still a clearly east-west line. Two-thirds of the distance is going to be on tangent Class 4 track geometrically a little faster than the current Fitchburg Line and with pretty wide stop spacing east of 495, so the Berlin-Clinton-Worcester curves can achieve a roughly equivalent schedule despite their slower speed. And you have run-thru options from Northborough for alt service patterns. Hell, if it matters that much you can even do the Leominster leg as a Central Mass branch instead of a Northborough extension to keep your butt from falling asleep after 2 hours in a commuter rail coach.
I think it'll take a significant reverse-commute job market in Worcester developing in the coming decades to really merit this, but Central Mass restoration makes a little more sense as a post-Northborough puzzle piece working towards Worcester. There's widespread agreement that Worcester will by midcentury be a reverse commute market. There's widespread agreement that the Worcester Branch will need to have some passenger use made of it to serve that reverse commute market before the area highways all choke. There's little consensus about any routes that can be fashioned off of upgraded existing track that'll serve that need (at least north and northeast of the city). And in a vacuum there's no there-there with just a Berlin/495 park-and-ride, plowing further north of Northborough for just a Boston commute, or confusing the audience for either of those ROW's by lumping in Fitchburg or any of the Fitchburg Line's catchment areas north of Clinton into a shotgun solution. I think the Central Mass might be worth a second look someday as a relatively cheap-to-implement Phase I of a "Worcester-North" commute pattern. After there's enough reverse commute growth to Worcester that some significant destination bleed-through starts showing itself in commute demographics around the Framingham/Sudbury/Acton dividing line (i.e. roughly the Route 27 corridor). 2050-era stuff not worth paying any mind to today, but keep that CM restoration study in the file cabinet because it may have another future life bootstrapped onto this context.
