Red Line jogger. MBTA surveillance photo.
The T had to stop inbound Red Line service from the south shortly after 7 a.m. to try to get this fool off the tracks between Andrew and Broadway. The T reports he managed to flee before police could detain him and ask what the hell he was thinking.
In the MBTA surveillance video below, he appears at around :05 (way, way at the top of the screen) and then hops onto the tracks around :35:
