The New York City Subway Lines Project:
M Train (Nassau St Local)

The M Train runs from Metropolitan Avenue in Queens, loops through Williamsburg, Brooklyn on its way into Manhattan for a very short stay in the downtown area before heading back into Brooklyn towards Bay Ridge. It runs local at all times in Brooklyn and Manhattan. It's another of the trains with an obnoxious schedule: it only runs from Chambers Street - Bay Parkway during rush hour, and late nights and weekends it only runs from Metropolitan Avenue - Myrtle Avenue.
