Mitch Warren has been the Executive Director of the Northeast Corridor Commission since 2011. He leads a staff that brings together the Northeast Corridor states and commuter rail agencies, Amtrak, and the federal government around a unified approach to rail investment. Congress authorized the Commission in 2008 to promote collaboration among its members on corridor-related planning and decision-making. In this role, Mitch led the development of the first-ever Northeast Corridor Commuter and Intercity Rail Cost Allocation Policy, which the Commission adopted in 2015. The Policy now allocates almost $2 billion annually in shared operating and normalized replacement capital costs and requires increased collaboration, transparency, and accountability among right-of-way owners and rail operators. In 2021, the Commission approved CONNECT NEC 2035, a collaboratively developed 15-year plan to rebuild and improve the Northeast Corridor. Later that year, Congress approved the Infrastructure Investment and Jobs Act, which provided $30 billion in guaranteed funding to begin to rebuild and modernize the corridor. In 2025, the Commission approved CONNECT NEC 2040, the latest update of the 15-year plan. Prior to the Commission, Mitch spent ten years working on transportation issues in the United States Senate, including with the Committee on Banking, Housing, and Urban Affairs; the Committee on Environment and Public Works; and the Committee on the Budget. He has also worked at Amtrak and in the private sector. Mitch received a B.A. from the University of Pennsylvania and an M.A. from the Princeton School of Public and International Affairs, and now lives in Silver Spring, MD.
