I like it too, but that area is loaded with wealthy NIMBYs who have expensive lawyers.
Yeah, but as we all know, NIMBYs aren't content to stop projects that are just near their back yards. The fact that this rail line concept is next to and spans a pond, and also in a wealthy suburb, is enough to set many a NIMBYs' heart on fire.
Newton is much more pro-transit suburb than most wealthy suburbs. This owes in part to its existing, fairly extensive, public transportation, and moderate density. The rate of single car commuting in Newton is fairly low (relatively speaking).
EDIT: The biggest obstacle would be selling as a net-positive transit-wise (increased -MU service to Auburndale, West Newton, Newtonville, Newton Corner) to offset people who would be upset due to their loss of CR tips.
I may be new to posting, but I've been observing this board for a while. It seems that extending the Blue Line to Kenmore via Storrow is most posters' preferred routing in various transit discussions. I'm curious how you think it should be done, and what would it look like in the end?
F-Line to Dudley said:Going west under Storrow to Kenmore in a rehash of the Riverbank Subway proposal from 100 years ago is probably the most viable one. If we ever reach the point where we want to tear down Storrow or bust it down to a leisurely undivided street through parkland there's almost going to have to be a 1:1 trade-in with transit. And in that case the Storrow EB roadbed pack makes an ideal re-use for a shallow subway tunnel, and the Storrow EB tunnel an excellent re-use candidate for rail and an Esplanade station at its widest point by the exit ramp. West of the tunnel the roadbed's in a cut below Back St. so you can pretty much build the tunnel in a half- above-ground box up to the level of Back St. and acting as the retaining wall for Back St. Similar to how the Red Line is in a surface-level box between Fields Corner and Ashmont...it's literally just an air rights cover-over there. It wouldn't have to support the weight of anything except grass on top, would be cheap construction (esp. around Mass Ave. where the cut gets deep), it would be waterproofed by virtue of being so shallow, and the Storrow WB roadbed can be used for your quiet 2-lane parkland drive. The only standard tunneling required is getting on-alignment to Kenmore from Charlesgate, and getting underneath the Kenmore Green level.
F-Line to Dudley said:If you bust down Storrow to 2-lane country road on the westbound carriageway the eastbound carriageway + road tunnel would be the Riverway footprint. Dig down to the bottom of the roadbed pack (incl. inside the road tunnel because you need about a foot's more height clearance, but the concrete floor probably does go down that far before reaching the rock ballast so that's trivial) and pour a box tunnel with roof level with the Back St. retaining wall, and landscape a grassy knoll on top of it with no load-bearing structures except for the street grid interfaces with "Storrow Lane". Roadway tunnel at the exit ramp would fit "Esplanade" station, and the deep cavity under Mass Ave. would fit that station and start your descent for the tunnel shiv under the Muddy River (I'm guessing metal-shielded insert with additional waterproofing) and the cross trajectory from Back St. to Beacon St. avoiding building foundations.
Cut-and-cover tunneling would be under the Embankment Rd. EB exit to Charles Circle, where one of the Charles MGH tail tracks would reach in front of the CVS. Then slice up the Embankment EB carriageway for a cut-and-cover to the road tunnel. More invasive and deeper dig under Beacon to "Kenmore Under", though the 3-lane width of the street and ultra-wide Beacon/Bay State Rd. split provides adequate buffer for avoiding building impacts. "Kenmore Under" can stub out at the Beacon/Comm Ave. merge in front of U Burger so the full station width doesn't have to underpin the Green level (i.e. platforms would span the Beacon/Raleigh intersection to basically the entrance of Cornwall's bar). Only whatever pair of storage tracks go further would actually slice diagonal under the Green level to keep the load-bearing footprint minimal.
Only tough tunneling here is the diagonal slip under the Muddy (which is going to need above-and-beyond waterproofing for the sea level rise era where Charles Dam can't empty the Basin as fast), under Beacon, and where it nicks the footprint of Kenmore station. On the Storrow EB carriageway it's way above the water table and the box tunnel's retaining wall sticking what's now about 3 ft. above the Storrow pavement acts as a flood wall if the Charles spills its banks. Embankment Rd. EB can have the crap torn out of its guts to impunity; there's not much in the way of utilities under the pavement of a de facto expressway that claimed ex-parkland. The Mass Ave. underpass retaining walls and auto tunnel are recyclable. And the Charles MGH tail tracks avoid all Charles Circle impacts.
It wouldn't be hard to build at all if post-Storrow era were achievable. It's mainly the wait for achieving the post-Storrow era that puts this out of current planning scope.

What alignment do you think works best? Following Storrow, or ducking into the Charles for a bit (like the Red Line at Fort Point Channel)? What about at Kenmore and the Muddy River?
Tunneled or cut and cover where it's on land? Or what about grade-level portions, for example if it consumed half of Storrow's right-of-way, to save money? Would Back Bay residents accept something like this in exchange for a downsized Storrow and less motor vehicle traffic noise?
Where stations would you include? Obviously Charles and Kenmore. But what about a Hatch Shell station, or a station at Mass Ave to connect with the 1? Would you remove Bowdown, as the T has proposed? Is it possible to keep it?
How would Kenmore look? Would you work it into the existing station, converting half of the tracks to Blue Line, or would you have a separate station, for example under Beacon Street, that's parallel to the existing station and connected via a pedestrian tunnel?
Where would you position the tracks after Kenmore for a future extension?
Perhaps this could go in the Crazy Transit Pitches thread, but I'm looking for a more in-depth discussion about implementation.
Nice post. An important piece was missing, though. Where would you point the stub tracks after Kenmore: Brookline Ave or Commonwealth Ave?
I'm also curious about the Fairmount Line. I think the lack of rapid transit service through this section of the region is criminal. Would it ever be feasible to convert this to a branch of the Orange Line? Notwithstanding difficulties in tunneling between Newmarket and Tufts Medical Center and actually connecting this to the existing Orange Line tunnel, is a rapid transit conversion of this line feasible, or does commuter rail (and potentially Amtrak) rely on it too much to give it over to a subway branch? Or is the ROW wide enough to keep both?
Before you even think about electrification or DMUs, just start running more service on the corridor! You could get down to 20-minute peak headways without running into too awful capacity issues at South Station.
Get to clock-facing half-hour every-day schedules, right now. Kludge together an ugly-but-works way to get free subway transfers at South Station, right now. Start coordinating bus schedules for good transfers, right now. You can do all of that for probably 2 million dollars a year, even with relatively inefficient loco-hauled trains.
The vehicle is not the service. The frequency, reliability, and transfers are the service. Jane Doe who lives on Morton Street isn't waiting for the line to be electrified to start using it; she's waiting for the knowledge that they'll always be a purple-colored thing waiting for her at :08 and :38 past the hour.
Once you have that minimum basic service, then you can start thinking about electrification, about using additional service and/or run-through capacity (which needs to be built for other lines regardless), about xMUs, about additional infills (Blue Hill Ave is definitely getting built - 100% plans are due this month for spring construction), about branding it as rapid transit lite, about using local buses as enhanced feeder services. But absolutely none of that should be talked about until the MBTA demonstrates an ability and willingness to run basic 30-minute-headway service with real transfer potential.

I could see a passageway being dug from the easternmost platform, which would become the designated Fairmount platform, with it's own fare lobby, under the little plaza between SS and the neighboring office building, right to the Red Line Station under Summer Street.
