Will the train be running from Paris and back again. Will the schedule change?
Paris trains will run normally on New Year's Eve December 31st. And a few of the lines (RER A, RER B, RER C/D plus a handful of Paris Metro lines) will run all night long through to the morning start time of 05:30 a.m. when normal service returns. During the all night operation of Paris RER and Metro service on New Year's Eve, the trains running will serve a reduced set of stations with less frequency than normal daytime service, but they will operate continuously throughout the night.
