With New York City’s annual St. Patrick’s Day Parade scheduled for Saturday, the MTA is reminding customers that alcohol will be banned from Metro-North Railroad.  Any alcoholic beverages found by the MTA Police will be confiscated.  Metro-North will operate extra trains to accommodate increased ridership on Saturday morning.  One additional train from Southeast, and one from North White Plains, plus one extra from New Haven, and one from Stamford will be on the schedule.  With large crowds expected, Metro North urged customers to buy round trip tickets in advance at their home stations or via their mobile ticketing app.
