Summit Avenue station (MBTA Green Line C branch)

Summit Avenue station (announced as Winchester Street/Summit Avenue) is a light rail stop on the MBTA Green Line C branch, located in the median of Beacon Street between Winchester Street and Summit Avenue in the Coolidge Corner neighborhood of Brookline, Massachusetts. The stop has two low side platforms that serve the line's two tracks; it is not accessible.

History
Until around 2004, the station was listed as Winchester Street to avoid confusion with Summit Avenue stop on the B branch. The B branch stop was closed as part of a pilot program in April 2004 (after which the C branch stop became Summit Avenue) and permanently closed the following March.

Track work in 2018–19, which included replacement of platform edges at several stops, triggered requirements for accessibility modifications at those stops. Design work for Summit Avenue and seven other C Branch stations was 15% complete by December 2022. Designs shown in February 2024 called for the platforms to be shifted eastward, with access from both Winchester Street and Summit Avenue. In May 2024, the Federal Transit Administration awarded the MBTA $67 million to construct accessible platforms at 14 B and C branch stops including Summit Avenue. , construction is expected to be complete in fall 2026.
