The Framingham/Worcester Line of the MBTA Commuter Rail system runs west from Boston, Massachusetts to Worcester, Massachusetts through the MetroWest region, serving 17 station stops in Boston, Newton, Wellesley, Natick, Framingham, Ashland, Southborough, Westborough, Grafton, and Worcester. The third-longest and second-busiest line on the system, the Framingham/Worcester Line contends with interference from freight trains, and a number of non-handicapped-accessible stations. Service on the line is a mix of local and express trains serving Worcester plus short-turn Framingham locals.
