No, the famous 9-euro ticket (and its 2026 successor, the Deutschlandticket, currently priced at €49–€58) is not valid for all trains. Specifically, it is restricted to regional and local transport. This includes all "RB" (Regionalbahn), "RE" (Regional-Express), S-Bahn, U-Bahn, trams, and city buses throughout Germany. It is strictly prohibited on high-speed, long-distance trains operated by Deutsche Bahn, such as the ICE (Intercity-Express), IC (Intercity), and EC (Eurocity). It also does not cover private long-distance carriers like FlixTrain or TGV services within Germany. In 2026, the rule remains: if the train is white with a red stripe (ICE), your budget monthly pass is not valid, and you will be fined for "fare dodging" if caught. To travel between major cities like Berlin and Munich on a 9-euro style ticket, you would have to take a series of slower regional trains, which might turn a 4-hour journey into a 10-hour odyssey with multiple transfers.
