MBTA "Transformation" (Green Line, Red Line, & Orange Line Transformation Projects)

I'm not aware of anything in North America with shared stops other than Seattle's downtown transit tunnel, but shared use there ended a few years ago. Pittsburgh's transit tunnel is shared, but there's no stops in it. Internationally I'm sure there are more examples, but the one I'm aware of is Stockholm Line 7.

Warsaw has several tram lines where buses also run.
 
In San Francisco, the F Market streetcar shares the center lanes of Market Street with several bus routes for 2 miles. The buses do tend to outpace the trains, but there's a stop every block that tends to reduce that disparity.

There are some overlaps between buses and Muni Metro on dedicated lanes for shorter distances - the K and 29 on Ocean, and the J and 22 on Church - but those are shorter distances.

The B is the only other one that (partially...to Packards Corner) has buses. And it would be a bunching disaster there with how brittle both the B's and the 57's schedules are.

There is also a big difference between Comm Ave and South Huntington in terms of roadway width. The buses don't really need the reservation, so much as they need single priority and queue jumping, both of which could easily be accommodated between Kenmore and Packard's Corner.
 
Has the original platform settled? Why else would they be raising it?

Its been a thing, but I don't know if the T ever explained why it became such an issue in 2023, but an informed guess would be the ... questionable... work done during the August 2022 pre-Eng monthlong shutdown.

Tree removal for C branch project has been approved by select board after NIMBYs went crazy and appealed the tree committee decision for loosing one tree that had to be removed due to type 10 bogies being wider than the existing cars.

The E reservation is narrower than both the B's and especially the C's. You wouldn't be able to fit two bus-width reservation lanes AND MAAB-width platforms AND turn lanes here, for instance. It's just a couple feet too shy from being able to fit.

How about using guided transitway?

Never seen an edit of what a type 9 on the mattapan line could look like. Not bad.

So out of sheer curiosity, I fed the same base picture into ChatGPT and asked it for a scheme based on the current / historic orange and cream livery the PCCs currently wear - notwithstanding the usual gen-AI artifacts, the Type 9s look good in orange ans cream.

It seems like not every intersection /needs/ turn lanes and this location left turns are probably better at Parker and if you realllllyyy need it - just create a U-turn lane to make a Michigan left at the firehouse.

I'm going to disagree about considering this being a "good" combination in that livery - the cream looks a bit sickly.

Love it. Looks way better imo than the red one.


Edit: Lol I fed your exact picture into chatgpt and told it to make the front sign say ashmont. I feel like now its a proper representation haha.

I tried to change the font to yellow but things started getting weird so this is the best I could do.

MBTA announces major Green Line closure to replace 130-year-old infrastructure​

MBTA


The MBTA will close a broad stretch of its Green Line for 15 consecutive days in December as it replaces a piece of the subway tunnels dating back to their original construction nearly 130 years ago.

From Dec. 8 through Dec. 22, the T will suspend service from North Station to Babcock Street on the Green Line’s B Branch, to Kenmore on the line’s C and D Branches and to Heath Street on the E Branch, the agency said.

“For a planned shutdown, this is huge,” Brian Kane, the executive director of the MBTA Advisory Board, said Tuesday when informed of the looming closure. “That’s the entire trunk [of the Green Line], basically. That’s major.”

MBTA Green Line closure Dec. 2025


While the lines are closed, MBTA work crews will replace a “wooden overhead catenary wire ‘trough’” running along the ceiling of the train tunnels, the agency said in a statement.

The trough, an original piece of the Green Line tunnels built in the late 1890s, houses the trains’ overhead wires.

The T said it will install “a modern, more durable, metal” replacement. Work crews will also use the closure to complete other projects, including the installation of a new Green Line safety system.

With Green Line service closed, the T will direct riders to fare-free shuttle buses, the Orange Line, which also runs through Downtown Boston, public buses and the commuter rail……..”
