Metro North is urging Santas around Connecticut to leave the beer at home.
All Metro North trains have been put under an alcohol ban while the annual event Santa Con takes place this weekend.
The event attracts thousands of people every year who dress as Santa Claus and attend various events in New York City.
Officials will be on the look out to confiscate alcoholic beverages and issue summonses carrying fines or imprisonment.
Violators may also be removed from the train.
