The Framingham/Worcester Line was chartered as the Boston & Worcester in 1831, the third railroad in New England, which later merged with the Western Railroad to form the Boston & Albany. Today, in addition to the MBTA the line sees Amtrak’s Lake Shore Limited and freight service by CSX, though the latter will be changing over the next few years as the T completes its purchase of the Framingham-Worcester section of the line and CSX moves out of Beacon Park Yard in Allston to a planned new yard in Boston’s western suburbs.

The line has had commuter service since the mid-1800s, which once included a circle route via the B&A’s Highland Branch (trains would head out to Riverside via the main line and back in on the branch, or vice versa. The Highland Branch is now the Green Line’s Riverside Branch.) Today trains terminate at both Framingham and Worcester. Several of the old B&A station buildings still survive, but most are used for non-railroad purposes today, the one in Framingham being the best known.
