Germany is closing the crucial Frankfurt-Mannheim railway line for five months to revamp its rail network, aiming to address frequent disruptions and delays. The 1.3 billion euro project by Deutsche Bahn includes refurbishing tracks, stations, and infrastructure, with plans to modernize 40 railway stretches by 2030. The closure will impact over 300 daily trains connecting major cities like Hamburg, Cologne, Stuttgart, and Basel, rerouting services and substituting regional trains with buses. The move follows frustrations during the European Championship, highlighting the urgent need for network upgrades due to outdated and overloaded infrastructure.
