Re: Green Line Extension to Medford & Union Sq

They are building up a temporary stabilized earth berm to support the drilling rig installing the noise wall foundations.

Pretty sure they've had track layouts final for quite some time, so it's probably in the docs archive of the project site.

No such luck with the carhouse. Funding for that dragging on so long, it ended up being downsized, and it'll be the very last thing constructed because it's not a prerequisite for service starts. There aren't publicly available schematics of all the revisions they're doing because it's lower-priority project deliverables. All we really know is acreage: the 2 buildings south of 3rd Ave. bordering the tracks are going to get blown up, and 2 of the 4 thru tracks wrapping behind BET (plus one freight siding attached to one of the buildings) are going away.

Re: Green Line Extension to Medford & Union Sq

I believe three tracks will remain between BET and the GLX Car house: CR east, westbounds and the 4th Iron. The Willey Track and the portion of the 3rd Iron which went to MS Walker are retired.

The original designs took no pity or had a clue on commuter operations, eliminated all but one through track.

Re: Green Line Extension to Medford & Union Sq

Will likely never happen, but would be nice if the extended D would skip over low-ridership Science Park (which will only get served by the E, kind of like how Savin Hill is Ashmont-only). It'd save only a minute or so since the D would still have to slow down to platform speeds. But it would help the Tufts-to-Government Center travel times stay competitive with driving. GC/Haymarket/NS/Science Park are four stops in roughly a mile of track.

Green Line isn't set up for regular expressing. It's only done when there's a headway to make up after a delay, where a train simply plows through a bunch of empty blocks to catch up with pace of traffic. There's no regular overtakes on rapid transit like there is commuter rail. Savin Hill isn't skipped; it's literally on a separate branch's tracks.


Science Park, while a low ridership outlier, has seen significant increases in recent years from all the nearby development. The gap used to be much wider. It would be one thing if it were stagnant, but it's actually growing at a healthy clip and should see that kick up a further notch with the multiple branch schedules coming via GLX.

Re: Green Line Extension to Medford & Union Sq

Agreed speed is critical, but rebuilding the Lechemere viaduct (in the CIP, currently in design) and redoing signals/track in the Central Subway (in design) will help in that area without needing to skip any stops.

Science Park is the closest GL stop to MGH, but it doesn't make sense for GL riders coming from the West to ride all the way through Downtown when getting off at Park and walking or switching to the Red Line would be faster. Once there's larger-than-token ridership GL coming from the North, I'd expect to see Science Park ridership increase for MGH access.

North of the Zinc.





On my way into the city this morning I noticed that the Maintenance & Storage Facility site was very busy. It looks like they have finished with the asbestos situation.

Re: Green Line Extension to Medford & Union Sq

I recall way back in the day, the plan was to do Union Sq first and get that running. Is that still the case?

I think it was more than Union would finish before Medford because it's shorter - it wasn't a dependency. Union indeed is scheduled for a 2021 opening.

Re: Green Line Extension to Medford & Union Sq

Quoting from what I wrote a while back on the Wikipedia article:

"In August 2012, the City of Somerville, MassDOT, and the MBTA reached a memorandum of agreement about the station. Through the Somerville Redevelopment Authority, the City will acquire $8 million worth of land for the station and grant the MBTA a permanent easement, while retaining the rights for transit-oriented development overhead. In return, the MBTA and MassDOT will pay for cleanup costs at the site, begin construction by the spring of 2014, and open the station no later than "late 2016-early 2017"

In October 2012, the Somerville Board of Aldermen approved the Union Square Redevelopment Plan and authorized an $8 million bond, including $6 million to purchase the land and $2 million for cleanup and station planning. In May 2013, the Board of Aldermen announced that the North Prospect block - a mostly industrial area bordered by the railroad tracks, Prospect Street, Somerville Avenue, and the rear of residential properties on Allen Street - had been acquired by the city via eminent domain for $4.5 million. The properties were to be vacated by August. The city also received a $1 million EPA grant to clean up one of the properties."

So yes, for a couple years the plan was for the Union Square Branch to be on an accelerated timeline. The city did their part, but the state did not.

Re: Green Line Extension to Medford & Union Sq

w00t! Signs of life at New Lechmere. That looks like a viaduct piling-to-be at the split between new and old.
