Boston Green Line Train Service Disrupted, Extension Adjustments Needed Amid Power Issues and Infrastructure Problems

Shuttle Buses Replacing Trains due to Power Outages; Repairs Needed on Green Line Extension Less Than a Year After Opening, Affecting 80% of Medford Branch and 50% of Union Square Branch

• Power problems disrupted Boston's Green Line train service, replacing train service on certain stretches with shuttle buses and prompting riders to seek alternative routes via Orange Line or Route 57 Bus.
• Less than a year since its opening, adjustments are required on the recently expanded Green Line, as rails on the Medford and Union Square branches were built too close together, potentially slowing down train speeds. This problem had reportedly been known within the MBTA project management but was only recently disclosed.
• There is uncertainty as to when the repair work on the rails of the Green Line extension will begin, though estimates suggest it might take several weeks. This misalignment affects roughly 80% of the Medford branch and 50% of the Union Square branch.
• The problems have drawn concerns and frustrations from residents, commuters, and business owners, particularly those in newly developed areas along the line, which were touted as benefiting from the transit line.
• Beyond the train line, the MBTA's plans to overhaul and electrify the bus system have also stalled. Two new electric bus facilities are facing delays and budget increases due to design modifications and global supply chain issues.
