T closing Porter, Davis, Alewife stations on four weekends

Postby Teamdriver » Wed Oct 17, 2012 12:39 pm

The MBTA will close the Red Line north of Harvard Square on four weekends in November and December in a continued effort to remove and replace corroded stretches along the track.

Buses will replace the trains along the stretch of the Red Line on the weekends of Nov. 17-18; Nov. 24-25, Dec. 1-2 and December 8-9, according to the MBTA

There is a slow order on the Orange Line between Forest Hills and Green. (It's only 5 years newer, same lousy construction) Wood in stone is the best way to lay track ... will they ever learn?

The next stop is Washington. Change for Forest Hills Trains on the Winter St. Platform, and Everett Trains on the Summer St. Platform. This is an Ashmont train, change for Braintree at Columbia.

Before Thanksgiving, after thanksgiving, and on another Christmas shopping weekend.

Same as last year -- they need to stop disrupting holiday travel and shopping. Ugh.

They also need to put the band-aids down and get out the surgical tools.

Is any of that floating slab even set up for ballast + wood conversion? The way the Alewife extension is constructed with the track bed acting as drainage channel I'm not sure if regular ballasted track would work well enough for that tunnel's drainage needs. They may be stuck with it.

It's no excuse for the deferred maintenance, though. They knew exactly what the rated lifespan was and exactly what excessive, unpatched water leakage would do to shorten that lifespan.

It seems like the Northwest Extension tunnel is in the worst shape of the T's subways- they really don't build them like they used to, I guess.

No...but if you let waterfalls flow unimpeded for 25 years, infrastructure's gonna break down. There is no reason whatsoever other than negligence that it was allowed to deteriorate into the condition that it it's currently in.

Porter Square: Built 115 ft below solid ground in 1983: Almost constant waterfall.

East Boston Tunnel: Built 80 ft below sea level underneath 50 ft of salty harbor water in 1904: Relatively minor leaks.

I think this is a classic case of "failure to think about potential problems". The East Boston Tunnel was built under conditions where water was expected to be a problem, so they dealt with water problems in its design. The Northwest Extension tunnel was built under conditions where water was not expected to be a problem, so they didn't deal with water problems in its design. Oops.

They need to do a full retrofit to capture and channelize the underground waterflow, but that's a complicated and expensive job, and the MBTA has had no appetite in recent decades for such things.

For years every high tide, Aquarium Station always leaked. There are some massive pumps in that tunnel!

Now to get back on topic...

The timing of this work is quite logical. Do outdoor work during the summer and work in the tunnels all winter. But if it is only a few more weekends worth of work, why can't this wait until after the New Year. Unless there is another major tunnel project coming?

Looks like a change in plans. According to the T...

Normal Red Line train service will operate between Alewife and Harvard Stations on Saturday, December 8th, through Sunday, December 9th, 2012. The scheduled weekend Red Line diversion has been cancelled and will be rescheduled for Spring 2013.

Could this be due to a longer period of time needed for the continued repairs/another forthcoming group of weekend diversions?

The postponement may be due to the Orange Line now being shut down between Ruggles and Forest Hills on the same weekend.
