Adam Fisher sets a record for traveling the entire MBTA system.

A 29-year-old subway enthusiast from Leicester, England, he visits every stop on the MBTA subway system in of 8 hours, five minutes and 16 seconds. In doing so, he surpasses the previous mark of just under 12 hours set by four Massachusetts Institute of Technology students in June 2013. Fisher documents the trip with photos and signatures of fellow passengers, but he declines to divulge his route, explaining, “I would be giving away some trade secrets. If someone else was to do it, I don’t want to give them pointers.”
