Someone in New York is pulling emergency brakes, destroying subway commute

That was how one MTA New York City Transit source with knowledge of the situation described the latest curiosity to befall the city’s beleaguered subway. Eleven minutes later, a New York City Transit employee on duty at 14th St-Union Square (one express stop uptown from Brooklyn Bridge) spotted another “surfer” on the back of an uptown 6 local train as it left the station. Every New York City Transit employee gave the same description of the “surfer” they saw riding the back of the train or darting across the tracks: young, male, wearing black clothing and white sneakers.
