British Transport Police and ScotRail are urging rail passengers to enjoy themselves but to make sure they stay safe on the railways this festives season.
Party-goers are being reminded that anti-social behaviour will not be tolerated and those who over-indulge run the risk of being refused rail travel.
In July, ScotRail announced a ban on the consumption and carrying of visible alcohol on its trains between 9pm and 10am and warned that those considered unfit due to the effects of alcohol could be prevented from travelling.
Passengers will notice an increase in high-profile British Transport Police patrols on trains and at stations to help make sure revellers enjoy their festive celebrations and get home safely.
Chief Superintendent Ellie Bird said: “BTP wholeheartedly supports ScotRail in its crackdown which serves to send out a clear message that anti-social behaviour fuelled by excessive alcohol is not acceptable.
“We will be working with our partners to make sure everyone can get to their office party or other event, and home again safely, and without hindrance from others.
