The funding is part of the MBTA's broader $10 billion Capital Improvement Plan, which includes $35.3 million specifically targeted at the South Coast Rail project.

Why it matters

The details

The MBTA's noise reduction efforts for the South Coast Rail will include installing sound barriers, upgrading track materials, and implementing other acoustic treatments along the rail corridor. These measures are intended to minimize the impact of train operations on nearby neighborhoods.

• The MBTA's $10 billion Capital Improvement Plan, including the $6.8 million for South Coast Rail noise mitigation, was released in April 2026.
