Generally, a Eurail Pass is not valid for city metro systems, subways, or buses. These local networks are typically operated by municipal transit authorities (like the RATP in Paris or TFL in London) rather than the national railway companies that participate in Eurail. There is a major exception in Germany, Austria, and Switzerland, where the pass is valid on S-Bahn (suburban) trains, which often run through city centers and function like a metro. For example, you can use your pass on the Berlin S-Bahn but not the U-Bahn. In Paris, it is valid on most RER lines but strictly excluded from the central Metro. In short, if the transit is run by the national rail carrier (like DB, SNCF, or ÖBB), it is likely included; if it is a dedicated city underground or tram, you will need to purchase a separate local ticket or pass.
That’s an excellent and very common question. The short answer is:
No, the Eurail/Interrail Pass is generally not valid for local city metro, tram, or bus systems.
Here’s a more detailed breakdown:
The pass CAN be used on commuter trains (like S-Bahn or RER) only when they are necessary to travel between two major cities or to reach a main station from an airport that is connected by rail.
Examples of valid use: Taking the Paris RER B from Charles de Gaulle Airport to Paris Gare du Nord. Taking the Berlin S-Bahn from Berlin Hauptbahnhof to Potsdam (a different city). Taking the Zurich S-Bahn from Zurich Airport to Zurich Hauptbahnhof.
Examples of NON-valid use: Taking the Paris Metro from the Louvre to the Eiffel Tower. Using the Berlin U-Bahn to get around the city for sightseeing. Taking a Munich tram from your hotel to the main station.
You will need to purchase separate tickets for local transportation in each city. Most cities offer convenient: Single or day tickets for their network. Tourist cards (like the Berlin WelcomeCard or Paris Vis
