The Long Island Rail Road's alcohol ban on late night weekend trains begins Friday.
Passengers will no longer be able to carry alcoholic beverages - opened or unopened - onto trains leaving Penn Station on Saturday and Sunday between midnight and 5 a.m.
Riders will also not be allowed to have alcohol on any LIRR trains between the same hours. Those caught will be issued a warning and their beverages will be confiscated, an LIRR spokesman said.
Alcohol will also not be permitted on all LIRR platforms during the same hours.
Police will be screening passengers boarding trains at stations across the LIRR's system. And signs explaining the new rule will be placed at city stations.
The ban follows two incidents in March during which conductors were assaulted by drunken passengers.
