1974 map of the MBTA. This was the first MBTA map in this style, including the commuter rail system under MBTA branding with a purple color. It contains a number of errors: the Haymarket North Extension is drawn to Wyoming, Fenway Park station is missing, a nonexistent commuter rail station is shown at Cummins Highway, and Chestnut Hill and Fields Corner stations are misplaced.
