Yes, the Eurail Pass is fully integrated with Deutsche Bahn (DB), Germany's national railway, and is one of the most effective ways to use the pass in 2026. It covers virtually all DB-operated trains, including the high-speed ICE (Intercity Express), IC (Intercity), and EC (EuroCity) lines, as well as regional trains like the RE (Regional-Express) and RB (Regionalbahn). A major advantage of using Eurail in Germany is that seat reservations are optional on almost all domestic ICE trains; you can simply board any train and sit in an unreserved seat. The only major exceptions are international high-speed routes—such as those to Paris, Brussels, or Copenhagen—and certain seasonal "peak" trains during the summer (late June to August), where reservations may be mandatory. Additionally, the pass covers the S-Bahn networks in major cities like Berlin, Munich, and Frankfurt, which are operated by DB. However, it does not cover U-Bahn (subways), trams, or buses, which are run by local municipal transit authorities. The 2026 Eurail app remains the primary tool for logging journeys and showing your digital pass to DB conductors.
