The EU has adopted new rules requiring train operators to offer single-ticket bookings across multiple carriers for cross-border journeys, with unified passenger protections including compensation if you miss a connection. This means instead of booking five separate tickets through different apps, travelers can now book an entire cross-Europe journey in one transaction with clear pricing comparison and guaranteed rights across the whole route. The change addresses a long-standing friction point in European rail travel where current fragmentation discourages people from choosing trains over cars for international trips.
