National rail service in Germany was completely halted for over an hour overnight between Tuesday and Wednesday due to a significant IT issue affecting the GSMR communication network. The disruption impacted train traffic across the country, according to reports from Reuters, Deutsche Welle, and Bild. Deutsche Bahn, the German railway company, has stated that service is returning to normal, though residual delays and disruptions are still possible. The root cause of the problem was identified as an IT malfunction within the critical communication infrastructure. Passengers experienced widespread travel chaos during the outage. Authorities worked to restore the system and mitigate the impact on commuters and freight transport. Full recovery is expected to take some time as schedules are adjusted.
