They don't sell beer or wine, but (unlike most European countries) you can't drink your own alcohol on Polish trains, only beer or wine bought & consumed in the restaurant or bar car.

In Poland, the legality of drinking beer on a train depends entirely on where you purchased the beverage. Under the "Act on Upbringing in Sobriety," drinking alcohol is generally prohibited in public spaces, which include train compartments and corridors. However, there is a major exception: you are permitted to drink beer or wine that you have purchased in the WARS restaurant car (the cafe/bistro wagon). You must consume the drink within the WARS area; taking it back to your seat is technically a violation of the law and can result in a fine if a ticket inspector or member of the railway police (Straż Ochrony Kolei) spots you. While enforcement can vary and some passengers discreetly drink their own beverages in private compartments, doing so openly is risky and culturally frowned upon if it disturbs others. To stay fully compliant in 2026, stick to the restaurant car for your refreshment.

In Poland, the regulations regarding drinking alcohol on trains depend on the operator and the type of train. Here’s a general overview:

1. PKP Intercity (Long-Distance Trains):
   Drinking alcohol is prohibited on most PKP Intercity trains, and staff may ask passengers to stop consuming it or confiscate the alcohol.

2. Regional Trains (Local Trains):
   Drinking alcohol is generally allowed on regional trains, but it’s always best to be discreet and respectful of other passengers.

3. Other Operators:
   Rules may vary depending on the train operator, so it’s advisable to check beforehand.

Important Notes:
- Public intoxication is illegal in Poland and can lead to fines or other penalties.
- Always follow the instructions of train staff and respect other passengers.

If you’re unsure, it’s best to avoid drinking alcohol on the train to avoid any issues.
