College which approximately replaced former elevated stations. Wellington was the northern terminus of the Orange Line until Malden Center opened on December 27, 1975, and some trains terminated at Wellington until Oak Grove opened on March 20, 1977. From February 1 to December 16, 1981, Malden Center and Oak Grove stations were closed on Sundays as part of systemwide austerity program. Wellington was the northern terminus of the line on these days, with a bus shuttle run to the closed stations. Wellington station was not originally accessible. Addition of elevators at Wellington and Sullivan Square began in 1991. The entire Orange Line, including Wellington station, was closed from August 19 to September 18, 2022, during maintenance work. Development In 1969, Mayor and State Representative John McGlynn sponsored the first of two bills to permit air rights development over the station and Route 16. The same year, Medford received a letter of agreement from the MBTA to build a parking garage over the tracks and the planned maintenance facility to free up development space. Unlike most MBTA stations, air rights over the station are owned by the city of Medford rather than by the MBTA. After city-done studies of population and land use, the Massachusetts Department of Public Works and the Federal Highway Administration held a study of several development options for Wellington, which would have involved air rights construction directly over the station. Options considered in this 1976 report included a minimum residential/transit deck, a moderate residential/transit garage, or a full-build shopping center, office, residential, nursing home, and transit garage. These plans also called for the 16/28 intersection to be partially grade separated, and a traffic circle to replace the blind underpass used for automobile and bus access to the station. Based on this study, the city of Medford continued to pursue development at Wellington. The preferred alternative in the 1981 Final Environmental Impact Statement included a parking garage built above the carhouse and rail yard, additional parking and a retail mall between the yard and Route 28, hotel and office space over the original parking lots, and condominiums and elderly housing northeast of the 16/28 intersection. Route 16 would have been placed in an underpass at the intersection, the ramps from 16 to the station parking improved, and a full park built along the riverfront. However, the planned developments were only partially built, and none of the planned interchange
