Eurostar will run dry trains during this summer's European Championships in France.
The train operator plans to ban all alcohol on a select number of services during the tournament, which runs for a month from June 10.
A company spokesman confirmed that alcoholic drinks would be confiscated from passengers if found at border controls ahead of certain services.
"Throughout the tournament there are two levels of alcohol restriction: zero alcohol, and limited alcohol," the spokesman told Reuters. "These are applied during specific days and time periods, and passengers on affected trains will be notified of the relevant details for their journey in pre-travel emails."
A predicted 2.5 million spectators are expected to visit France for the tournament that consists of 51 matches involving 24 national teams.
Alcohol restrictions aren't new for Eurostar. The company has imposed similar drink bans on ski-resort trains and during rugby union's Six Nations when England play France in Paris.
