[4] The Dorchester Branch (Midland Route) was reopened as a bypass in November 1979 during Southwest Corridor construction, including stops at Uphams Corner, Morton Street, and Fairmount.

[1] Uphams Corner and Morton Street were dropped effective January 30, 1981 as part of systemwide cuts.

The station was not accessible, since service over the route was intended to be temporary; however, it was popular with residents of the communities the line passed through.

[1][6] In September 2005, the MBTA awarded a $6.5 million contract to rebuild the station as part of the Fairmount Line Improvements project.

[3] In 2014, MassDOT replaced the structurally deficient bridge carrying Morton Street over the Fairmount Line tracks.
