(MBTA) board unanimously approved its proposed Capital Investment Plan (CIP) for fiscal years 2027 to 2031 on May 28. The five-year plan outlines spending of $10.3 billion across 660 capital projects. Focus will be on regular maintenance, modernization projects and improved service.

“We are strategically planning to deliver capital projects that deliver meaningful benefits, improve service, and ensure safety to meet and exceed the needs of today and future generations,” said Interim Secretary of Transportation and MBTA General Manager and CEO Phillip Eng in a press release.

Major rapid transit projects include upgrades to signal and power infrastructure, passenger accessibility improvements, station modernization and track improvements, including programmed diversions and track renewals.

Regional rail will see the replacement of the oldest locomotives with battery-electric and low-emissions diesel locomotives, and the replacement of remaining single-level coaches with bi-level coaches. Modernization efforts include a six-track electrified layover facility at Boston’s Widett Circle and the replacement of the 1930s-era North Station Draw One Bridge.

is available for public review; it includes an overview of the planning process, the full list of capital projects and anticipated funding levels. The plan goes into effect July 1.
