context_page_description: The Red Line is a rapid transit line operated by the Massachusetts Bay Transportation Authority (MBTA) as part of the MBTA subway system. The line runs south and east underground from Alewife station in North Cambridge through Somerville and Cambridge, surfacing to cross the Longfellow Bridge then returning to tunnels under Downtown Boston. It continues underground through South Boston, splitting into two branches on the surface at JFK/UMass station. The Ashmont Branch runs southwest through Dorchester to Ashmont station, where the connecting light rail Ashmont–Mattapan High Speed Line continues to Mattapan station. The Braintree Branch runs southwest through Quincy and Braintree to Braintree station.
  The Red Line operates during normal MBTA service hours with six-car trains. The 208-car active fleet consists of three orders of cars built in 1969–70, 1987–89, and 1993–94. A 252-car order from CRRC is being built from 2019 to 2023. The Red Line is fully grade-separated; trains are driven by operators with automatic train control for safety. Cabot Yard in South Boston is used for heavy maintenance and storage; yards at Alewife, Ashmont, and Braintree as also used for storage.
context_section_description: A 1979 renovation of Park Street added two elevators, making it the first accessible station on the Red Line. In the early 1980s, the MBTA began extending platforms for six-car trains: Ashmont and Shawmut in 1981, Charles/MGH in 1982, and Fields Corner and Savin Hill in the mid-1980s. (The Northwest and South Shore extensions had been built for longer trains, while JFK/UMass had been modified in 1970.) In the mid-1980s, the MBTA spent $80 million to extend the platforms of seven underground Red Line stations (Central, Kendall/MIT, Park Street, Washington, South Station, Broadway, and Andrew) and three Orange Line stations. Six-car trains entered service on January 21, 1988. 
  Central, Kendall/MIT, Park Street, and Downtown Crossing (renamed from Washington in 1987) were completed in 1988. A major reconstruction of JFK/UMass added a platform for the Braintree Branch, which opened on December 14, 1988. Renovations to Broadway were completed in October 1989. Quincy Adams and Braintree were accessible by 1989, if not from their original construction. South Station was completed around 1992, followed by Andrew in 1994.
  The 1990 passage of the Americans with Disabilities Act spurred the renovation of additional stations. Quincy Center was modified in 1991, followed by North Quincy in 1998. Charles/MGH was rebuilt from 2003 to 2007. The agency began design for the four Ashmont Branch stations in 2001. Savin Hill was closed from May 2004 to July 31, 2005 for reconstruction. It was followed by the completion of the rebuilt Fields Corner station in 2008, the modified Shawmut in 2009, and the rebuilt Ashmont in 2011. The final Red Line station to be modified for accessibility was Wollaston, which was closed from January 2018 to August 2019 for a complete reconstruction.
