As if the trains didn't have enough trouble, last night an idiot went and decided it would be a fun idea to walk on the train tracks on the Williamsburg Bridge. The track-walker started trekking down the tracks around 12:25 a.m. bringing the J train to a halt. He was soon nabbed by cops and service resumed a little after one a.m.. Why the man chose to walk on the tracks when the trains were finally running again, we have no idea. Perhaps that is why he has been taken to Woodhull Hospital for psychiatric observation?
