Boston Green Line Upgrades 130-Year-Old System

MBTA shuts Green Line for 9 days to replace 130-year-old infrastructure, install safety systems

MBTA Suspends Green Line Dec 6-14

Boston's Green Line will shut down between North Station and Babcock Street for nine days starting December 6, transit officials said. The MBTA announced the suspension will run through December 14 to replace 130-year-old infrastructure and install modern safety systems. Shuttle buses will replace train service on the B, C, and D branches, while E branch trains will operate only between Heath Street and Prudential during the closure.

Century-Old Infrastructure Gets Overhaul

The work focuses on replacing wooden overhead catenary wire infrastructure that's been in service since approximately 1897, according to the transit agency. Crews will remove the aging wire trough system that powers Green Line trains and install updated components designed to improve reliability. Workers will also continue installing the Green Line Train Protection System, a modern safety platform that helps prevent accidents. The MBTA didn't disclose the total cost of the infrastructure improvements in its announcement. Transit agencies typically schedule major electrical work during extended service suspensions to maximize efficiency and worker safety.

Multiple Branches Face Service Changes

The suspension affects most Green Line branches that normally serve the North Station-to-Babcock Street corridor, officials said. Shuttle buses will provide replacement service for riders on the B, C, and D branches during the nine-day closure. E branch service will operate on a shortened route between Heath Street and Prudential only, requiring transfers for riders heading to North Station or points between. The MBTA characterized this as a high-severity service change but didn't provide specific ridership impact numbers. Officials said the work schedule was designed to complete multiple infrastructure projects during a single service disruption rather than requiring repeated future closures.

Riders Should Plan Alternative Routes

The suspension runs from Friday, December 6 through Saturday, December 14, with normal service resuming December 15. Commuters should visit the MBTA website for shuttle bus schedules and alternative route information, officials said. The agency typically provides detailed service advisories several days before major suspensions, though specific shuttle bus deployment numbers weren't available. Moovit provides real-time updates for MBTA routes and automatically reflects service changes when they take effect, helping riders navigate disruptions.
