On October 8, 2026, the Massachusetts Department of Transportation and CSX Transportation announced an agreement to fund and carry out rail improvements in the Berkshires. The plan is intended to support a permanent seasonal weekend Berkshire Flyer service and to lay the groundwork for broader passenger‑rail expansion in western Massachusetts.
The upgrades will add infrastructure needed to sustain ongoing weekend service and to enable future passenger‑rail options, building on the existing seasonal Berkshire Flyer that operates in the region.
