A proposal has been introduced to expand the Massachusetts Bay Transportation Authority (MBTA) Commuter Rail service to Cape Cod, aiming to provide a new transit option for residents and visitors. The plan, discussed in recent public meetings, would extend the existing Middleborough/Lakeville line to a terminus in Buzzards Bay or beyond, potentially reducing traffic congestion on the Sagamore Bridge during peak summer months.
According to the Cape Cod Commission, the proposal is in early feasibility stages, with studies examining ridership potential, infrastructure costs, and environmental impacts. The Cape Cod Regional Transit Authority has expressed support, noting that seasonal demand surges each summer, with over 5 million visitors annually. No official timeline or funding source has been confirmed as of May 2026.
Key challenges include upgrading existing freight rail tracks owned by Mass Coastal Railroad and addressing concerns about noise and wildlife disruption. The project would require coordination between state and local agencies, as well as federal grants. A public comment period is expected later this year.
