The Massachusetts Bay Transportation Authority (MBTA) began funding Eastern Route service in January 1965, and stops at the plant resumed on September 9, 1965.

River Works station is proposed to be opened to the public and made accessible as part of plans for a development on adjacent land.

The location is also a potential station site for a proposed extension of the rapid transit Blue Line to Lynn.

The River Works complex surrounds the station on the north and west; an undeveloped site (formerly part of the plant) is located to the east.

[10][11][12] Within days, high passenger volumes led the railroad to authorize construction of larger stations at West Lynn, Revere, and Winthrop.

[17] On March 29, 1910, a Boston-bound express train from Portland derailed at the freight yards just west of the station; despite the damage to the locomotive, there were no serious injuries.

[27][28] By 1917, a small number of local trains stopped at River Works, about 1 mile (1.6 km) south of West Lynn; it was gone from timetables by 1929.

[29][30] The plant was expanded during World War II; the stop appeared as a timetable note for two weekday inbound trips in 1946, and one in 1952.

[1] River Works and Lynn stations were changed from fare Zone 2 to Zone 1A (allowing subway-fare rides to Boston) from May 22–31, 2020, and July 1, 2020 – June 30, 2021 to provide additional travel options during the COVID-19 pandemic (as many of the 400-series bus routes were reduced in frequency) and to examine the impact of temporary fare changes.

[39][40] The change was found to have diverted just 8 daily riders to commuter rail, and the stations reverted to Zone 2 on July 1, 2021.

Four years prior to the closure, the city upzoned the 77-acre (31 ha) site to allow buildings up to 20 stories high in hopes of attracting new commercial development.

The state was hesitant to pay for such upgrades without proven ridership, and GE would require security considerations before approving the public opening.

[44] However, under a tentative agreement that the developer reached with the Massachusetts Department of Transportation in February 2017, the rebuilt station would be open to all riders.

The 1945 Coolidge Commission report recommended an extension over the BRB&L route, with a West Lynn station at Commercial Street.
