Blue Line (MBTA)

Blue Line (MBTA). The Blue Line is a rapid transit line in the MBTA system, serving East Boston, the North End, and Downtown Boston. It runs from Bowdoin in Boston to Wonderland in Revere, connecting to key intermodal hubs like State and Airport. As the MBTA's shortest heavy rail line, it provides a critical link to Logan International Airport and the Boston Harbor waterfront.

History

The line's origins trace to the privately-owned East Boston Tunnel, which opened in 1904 for streetcars operated by the Boston Elevated Railway. The tunnel was converted to rapid transit standards in the 1920s, with service extended to Wonderland in 1952 and 1954. The line was officially designated as the Blue Line in 1965 as part of the MBTA's system-wide color-coding. Major projects included the 1924 opening of the new underwater tunnel and the 2004 addition of the modern Airport station, featuring a direct shuttle bus link to Logan International Airport.

Route and stations

The route begins underground at Bowdoin near Government Center, traveling under Boston Harbor via the East Boston Tunnel to Maverick. It emerges to an elevated structure in East Boston, serving Airport station before transitioning to a surface route along the Revere Beach Parkway. The line passes through Suffolk Downs and Beachmont before terminating at the Wonderland station park-and-ride facility in Revere. Key transfer points include State station for the Orange Line and Government Center station for the Green Line.

Rolling stock

The Blue Line fleet consists exclusively of Siemens Type 7 vehicles, built between 2007 and 2009. These 94-foot cars operate in permanently coupled four-car sets, powered by a 600-volt DC third rail. The Type 7 fleet replaced the aging 0600-series cars from the Pullman-Standard and the H. K. Porter Company. Maintenance is performed at the Bennett Street facility in East Boston, with the cars designed to handle the line's mix of underground, elevated, and at-grade operations.

Operations

Trains operate from approximately 5:00 AM to 1:00 AM daily, with headways of 5–6 minutes during peak periods on the MBTA schedule. The line interfaces with other MBTA services at several stations, including connections to Commuter Rail at Government Center station and ferry services at Maverick station. The MBTA Police patrol the line, and operations are monitored from the Rail Operations Center in Boston. Special event service is often provided for games at the adjacent TD Garden and Fenway Park.

Future plans

Long-term proposals include a westward extension from Bowdoin to Charles/MGH station, creating a direct transfer to the Red Line and better serving Massachusetts General Hospital. The MBTA's capital investment plan also includes station modernization projects, such as accessibility upgrades at Maverick station. Studies have evaluated potential further expansion into Lynn and Chelsea, as outlined in the Central Transportation Planning Staff's regional needs assessments.
