The upcoming improvement project will require two extended four-month closures. In addition, Blue Line service to Willowbrook/Rosa Parks Station will be closed for eight months while the station is rebuilt with more capacity, a new customer service center and community plaza, easier connections to local buses and surrounding communities, and upgrades to safety and security systems.
Work on the Blue Line will include improvements to the signaling, tracks, and overhead wires that delivers the electricity to power the trains. Four new crossover tracks will be built to reduce service interruptions. There will also be numerous station improvements, including new interactive digital map displays for all stations, which will display train arrival and departure times, service alerts, and maps of the system and nearby area. Other visible amenities will include new signage and landscaping.
The Metro Board of Directors recently approved the naming of rail lines with letters and colors to accommodate a growing system and make the rail and bus rapid transit network easier to understand and more custom friendly. Upon completion of the entire New Blue Improvement Project, the new name for the Blue Line will be the “A” Line with the color blue.
The announcement highlights the long-standing partnership between the Class I railroad and the commuter rail system, dating back to Metra's creation in 1983.
Crews completed a significant portion of the testing required before commissioning the new, digital signaling system, which will bring important upgrades that strengthen Red Line service reliability for riders and provide Red Line Operations the ability to route trains more quickly, turn trains around faster, and recover from unplanned disruptions more efficiently, said MBTA officials.
In addition to new projects, progress continues on a multiyear effort to upgrade track, electrical, and signal systems on the Metra Electric Line to accommodate the expansion of service on the South Shore Line.

The Peninsula Corridor Joint Powers Board recently met for a budget workshop, during which staff outlined the significant service reductions Caltrain could be forced to make without new external funding.
Funding for the purchase of the railcars comes from the nearly $220 million in additional capital dollars Gov. Josh Shapiro allocated in November 2025 to support urgent safety upgrades and infrastructure improvements.
With major events and increased travel expected across the state this summer, the Administration is focused on making sure people have a reliable, affordable alternative to driving so we can reduce congestion, support daily commuters, and keep Massachusetts moving.
