The City’s Sharpest Transit Mind Doesn’t Even Work for the M

Diamond has been a folk hero among train aficionados for some time, but recently he's crossed into the mainstream. Using his online handle, Diamond curates a popular (among train geeks) YouTube channel, posting videos that document the various idiosyncrasies he discovers along the system's more than 600 miles of track. He'll sometimes spend hours shooting footage for what will eventually amount to a three-minute clip. His videos capture ordinary trains doing ordinary things, although their titles sound like Star Wars erotica — "R62A and R188 7 Train Action at 46th Street," anyone? That video, one of his greatest hits, is nothing more than ten minutes of trains pulling into and out of a station. It has more than 95,000 views.
