Didn't hear a air pop so i assume they probably took a split or full service which is the next quickest way to stop a train without going into emergency
nice! ...fun fact, but that first hopper on the second local has one of the most famous graffiti writers on it, 'zephyr', very rare and cool to see! he started doing graffiti in the late 70's and pioneered it, he's a legend in his own right.... he is featured in an old documentary from the 80's about nyc subway graffiti called 'style wars' - the more you know! thanks and always enjoy the videos.
