The Green Line's central tunnel reopened October 5 after nine days of signal work. Crews installed 40 of 72 planned miles of new cable and 85% of junction boxes. Another nine-day closure starts November 7, with more shutdowns set for late October and December.
Meanwhile, new Red Line cars are delayed again. The T now expects the last of 252 cars in the early 2030s, not 2027, after U.S. customs seized car shells over forced-labor concerns. The T has accepted 68 cars so far.
Why it matters

Scenarios
1
Shutdown pace continues into 2027
Likely
Resolves by Q2 2027
Discussed by: MBTA spokesperson Lisa Battiston, who said more outages are 'likely' in 2027
With only 15% of Green Line signal cabling installed and a $25 billion backlog, the T has plenty of work left. Officials have already said more shutdowns will come in 2027 to prepare for new train cars. Riders face another year of disruption.
2
Accelerated program delivers, service normalizes
Possible
Resolves by End of 2027
Discussed by: MBTA COO Ryan Coholan and board member Mary Skelton Roberts
The prolonged shutdowns finish the bulk of the work by end of 2026. Slow zones stay eliminated, trains run at higher speeds, and the T returns to routine maintenance. This outcome validates the strategy as a worthwhile tradeoff.
3
Political backlash forces schedule changes
Unlikely
Resolves by Jul 1, 2027
Discussed by: Boston Globe coverage of rider frustration; transit advocates
Rider outcry grows loud enough that the Massachusetts legislature or governor pressures the MBTA board to cap shutdown lengths or require longer notice periods. The T reverts to more piecemeal work, slowing the catch-up program.
4
Shuttle-dependent years stretch into 2029
Likely
Resolves by Apr 1, 2027
Discussed by: MBTA procurement filings reported by NBC Boston
The T plans to spend about $5 million a month on replacement shuttle buses from April 2027 through March 2029, with contracts possibly extended to 2032. That signals service disruptions will continue well beyond the current round of Green Line signal work. More shutdowns are already flagged for 2027 to prepare for new train cars.
5
Type 10 Train Debut Slips to 2028
Unlikely
Resolves by End of 2027
Discussed by: MBTA General Manager Phil Eng
Eng says the signal upgrades now underway are 'essential' for the new Type 10 cars, which have 50% more capacity and are on track to begin service in 2027. If the signal work falls behind, the fleet's debut could slip, extending the shutdown program.
Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1 of 3
June 2016 – June 2017
DC Metro SafeTrack (2016)
Washington's Metro launched SafeTrack, a 16-month program of extended single-tracking and weekend shutdowns to fix a track repair backlog. It followed deadly smoke incidents and years of deferred maintenance.
Then
SafeTrack disrupted riders for over a year but completed in June 2017, addressing more than 1,000 track-related defects.
Now
Metro's reliability improved, though financial troubles continued. SafeTrack is now seen as a model for aggressive catch-up maintenance.
Why this matters now
Direct comparable to the MBTA's prolonged shutdowns, showing how one agency's painful year produced lasting reliability gains.
2 of 3
June 2017 – 2020
NYC Subway State of Emergency (2017)
Governor Andrew Cuomo declared a state of emergency after a series of derailments and signal failures on the New York City subway. New transit chief Andy Byford launched a catch-up program with frequent night and weekend closures.
Then
The emergency declaration freed funding, and Byford's program improved on-time performance and reliability by 2020.
Now
Byford resigned in 2020 over a funding dispute. Many ambitious projects remain unfinished, showing how political support can falter.
Why this matters now
Shows the promise and fragility of a catch-up maintenance strategy driven by a new transit chief facing a huge backlog.
3 of 3
January – March 2015
MBTA Winter Crisis (2015)
Record snowfall crippled the MBTA, causing days of suspended service and stranding thousands of riders. The system's aging infrastructure and poor snow-fighting equipment were blamed.
Then
Governor Charlie Baker formed a review panel, which recommended major capital investment in the T.
Now
The crisis exposed years of underinvestment, leading to some funding increases but not enough to prevent the current maintenance backlog.
Why this matters now
Shows how deferred maintenance compounds: underinvestment today turns ordinary shocks into system failures later.
