Chelsea station is a Massachusetts Bay Transportation Authority intermodal transit station located adjacent to the Mystic Mall in Chelsea, Massachusetts. It is the terminus of the SL3 route of the MBTA Silver Line bus rapid transit network, and is served by the Newburyport/Rockport Line of the MBTA Commuter Rail. The accessible station has a loop with two small platforms for the Silver Line, and two full-length side platforms for commuter rail trains.
East Everett station, located near the modern Chelsea station, was served by the Boston and Maine Railroad and predecessor Eastern Railroad from 1880 until around 1950. Prior to its 2010 cancellation, the Urban Ring Project planned for a circumferential BRT line with a stop at Mystic Mall.
