Understanding the Eurail Logic
October 12, 2025
The "15-Minute" Rule in Germany vs. Switzerland
One of the most common anxieties for rail travelers is the short transfer window. If you are routing through Zurich HB or Bern, a 12-minute transfer is usually safe. The Swiss Federal Railways (SBB) run on a "takt" system designed specifically for these synchronized transfers.
However, if you are transferring in Frankfurt or Hamburg, the situation is different. In 2024/25, Deutsche Bahn has struggled with delays on long-distance ICE lines. A 15-minute connection in Germany is risky. I always recommend manually adjusting your search filters to allow for at least a 40-minute buffer if you have a checked bag or are traveling with family.
The Hidden Cost: Seat Reservations
A common misconception is that the Eurail pass covers everything. It covers the ticket, but not the seat on high-speed lines. This catches many backpackers off guard in France and Italy.
- France (TGV): Mandatory reservation fee (~€10-20). These sell out weeks in advance in summer.
- Italy (Frecciarossa): Mandatory fee (~€13). Usually available even a few days before.
- Germany (ICE) & Austria (Railjet): Reservations are usually optional. You can hop on without one, but you might have to stand or play musical chairs.
Regional Trains: The "Free" Alternative
If you want to save money and avoid reservation stress, toggle your planner to "Avoid High-Speed Trains." A trip from Lyon to Marseille takes longer on the TER (Regional Express), but it is completely free with your pass and the scenery along the Rhône valley is superior.
