Fitchburg Line's 4-track width. If you view the corridor from any street you'll see the slightly overgrown extra track berths on each side traced by the retaining walls and property fences. It's exactly the same upstream as it is on GLX out to Union. The only obstructions to square south of Beacon St. are:How are you going to bring a Porter Square Green Line extension into Porter Square? I don't see where there's room for it anywhere.
Single-track ops...shift track waaaaaay to one side while half the ROW gets trenched. Then waaaaaay to the other side on the propped up half-roof when the other side is trenched. Small temp portable mini-high platform set up on the other side of the Mass Ave. overpass in the interim, accessible from the existing stairs. For ADA access from the temp platform, grade the eventual Alewife bike path access ramp up along the Passage to India rear lot to the sidewalk and use that. Flip the temp mini-high to the other track when it's time to trench the other half.Just wondering; how disruptive would Porter-GLX be to Fitchburg MBCR operations? I'm assuming that service would be suspended outright during the box-tunneling/trackbed lowering.
That they can do today if they wanted. It pinches at the end because of the need back in 1982 for keeping the old CR platform (still visible as derelict ruins underneath the Somerville Ave. overhang) in-service uninterrupted during station construction. The tapered end is where old and new had to overlap in shared space. Re-spread the tracks onto the old platform berth and you can get a full regulation 800' x 12' uniform width full-high island platform put in.Would this also finally get rid of the super narrow island platform at the Porter CR station?
State ownership of the Watertown Branch ROW ends at School St. slightly past Watertown Mall. The section past there to the Square was abandoned much earlier, in 1960, and reverted to private ownership. It's largely intact, however, except for the Lexus dealership that got plopped right on the ROW. Rest of the properties are scuzzy industrial backlots...some of them still with tracks in the back.Say the Green Line gets extended to Porter. How feasible would it be to extend it a little further along the Fitchburg right-of-way and then pull off south behind the Fresh Pond Mall, skirt along the East side of Fresh Pond, and end in Watertown?
Sure it would. The 71 draws more daily riders than SL2 + Silver Line Way short-turns on the Transitway. And takes over a half-hour at peak to get between Harvard and the Square and regularly gets stuck in traffic. Single fare out of Harvard, 1 stop in the reverse-commute direction, and transfer to Green Line beats the bus every time, with 1-1/2 times the frequencies. Why wouldn't the north end of the E's run end up clocking in at about 70-75% of the E branch's dedicated ridership with those advantages coupled with the exploding growth in North Cambridge and East Watertown. For one, you currently cannot get to Watertown at all from North Cambridge without slogging it to Harvard and getting on the bus. Watertown may as well be on the Moon for anyone in Somerville or anywhere on the 77.Not hard but too round-about to make for usable service. Anyone coming from Watertown via bus heads to Harvard or Central. Sending them up to Alewife and Porter wouldn't attract enough ridership.
Sure it would.
Busway on the H2O Branch might have some environmental issues. When the state bought the branch from Pan Am 2-1/2 years ago, the portion of ROW that goes through the Waterworks property--and only that portion--was conferred to City of Cambridge ownership. Believe that was some sort of paper trick for streamlining continued funding of the city's soil runoff mitigation efforts ringing the whole perimeter of the reservoir. It is a fully landbanked RR on their property subject to the 'interim use' provisions of that federal law, but that does mean potential fly in the ointment is City of Cambridge's say in future use, and the environmental impact that future use would have on the reservoir.Gee sounds almost like the Yellow Line (or a section of it) "crazy transit pitches" post I made earlier this week.
I created a busway from Alewife to Watertown Sq using a exiting bike path and abandoned ROW. (along with an entire BRT line to Wonderland via RBP/MVP/MA-16)
And I agree, as a former North Cambridge resident, I often wanted to go to Watertown (think the yummy diner) and it's a pain in traffic. By putting a busway in, it would lower the headway (even though it's further away) because it wouldn't have to contend with traffic. (if done right)
Yeah I agree. My transit pitch was kinda crazy anyways (more because we'd need to re-use a rail trail and those are pretty hard to do). I did not take in considering environmental concerns into my design, as it's a off the cuff proposal.Busway on the H2O Branch might have some environmental issues. <snip> <snip>
It's not BRT because there isn't an available injection point for the busway, but as Yellow Line infills go that's screamingly obvious. Base the schedule on padding for the slog around the parkway, where very few stops are going to be needed, and then Huron + Grove/Arlington + Arsenal is a fairly reliable schedule. It's fast in the car...I'd just kill not to have to do that in the car every single time.
Those tracks are spoken for. That's the Massport-owned Mystic Wharf Branch to Moran Terminal/Boston Autoport. It's presently out-of-service, but Pan Am has active freight rights on it which it has not relinquished. And much like Track 61 down in Southie, Massport has long-range plans to bring the freight trains back to the port.Maybe this belongs in crazy transit pitches thread, but I was looking at a map of Charlestown and noticed that in between Community College and Sullivan Square, there is a rail spur breaking off under I93 at about D street, that then curves around and runs parallel to Medford St. If UR was ever built as light rail, would it be viable or even worth it to have a spur running along this side of Charlestown? It seems to me that for half of the neighborhood, this would be better transit access than walking to the orange line, especially depending on the destination. I have no idea if this would make any sense from an ops standpoint, or if it would even be possible or wanted by the neighborhood. In fact now that I think about it, maybe that rail spur is actively used for freight? Am I way off target here or would this be useful idea if UR were ever built?
