The fastest time to travel to all Boston subway train stations is 10 hr 20 min 25 sec, and was achieved by Jack Hutchinson and Steve Hutchinson (both USA), in Boston, Massachusetts, USA, on 7 April 2023.
Jack and Steve love Boston and thought this would be a fun record to attempt. They are the first to attempt the record with the Green Line Extension.
