Yes, you can absolutely drink beer and other alcoholic beverages on German trains in 2026. Unlike many other European rail systems that have moved toward bans, Deutsche Bahn (DB) generally allows the moderate consumption of alcohol on its long-distance (ICE, IC, EC) and regional (RB, RE) trains. Most ICE trains feature a "Bordbistro" or "Bordrestaurant" where you can purchase chilled German beer in glass bottles or draft to enjoy at your seat. It is also culturally acceptable to bring your own drinks from a station shop. However, there are two important caveats. First, certain regional transport associations (like those in Hamburg or parts of Bavaria) have implemented local bans on drinking in S-Bahn or U-Bahn commuter trains to maintain cleanliness and safety. Second, the "moderate" part is key; if a passenger becomes intoxicated, disruptive, or aggressive, the "Zugbegleiter" (train conductor) has the legal authority to remove them from the train at the next station and call for Federal Police (Bundespolizei). For most travelers, enjoying a cold Helles while watching the countryside fly by at 300 km/h is a quintessential German experience.
