Funded with a High-Speed Intercity Passenger Rail (HSIPR) grant from the FRA in 2010, the South Station Expansion Project (SSX) is intended to expand station terminal capacity and related layover capacity in order to meet current and anticipated future high-speed, intercity, and commuter rail service needs. The expansion of South Station will enable growth in passenger rail transportation along the NEC and throughout the greater New England region. The project will also improve passenger experience, promote development in a progressive area of Boston, and allow for Dorchester Avenue along the Fort Point Channel to be reopened for public use for the first time in decades.

Amtrak is working with MassDOT to complete the first phase of the project, which includes planning, state and federal environmental review, preliminary engineering, up to 30% design, and a layover facility alternatives analysis.

Amtrak is also coordinating with MassDOT and the MBTA on the proposed South Station Air Rights (SSAR) Project, within the immediate station terminal footprint. SSAR is a mixed-use transit-oriented development led by Hines Development and Gemdale Properties.
