Overview
- A signaling system malfunction at Hannover Hauptbahnhof on Ascension Day halted all traffic until around 9:30 AM as technicians were en route.
- An overhead wiring issue on track 453 reported Sunday at 8 PM has since triggered further delays and cancellations across regional Sprinter, Westfalenbahn and Metronom lines.
- ICE and IC trains have faced up to 30 minutes of delays or rerouting to Hannover Messe/Laatzen while repair crews work under pressure.
- Deutsche Bahn points to aging technology—some systems date back to the early 20th century—and persistent personnel shortages as drivers of recurring faults.
- Crews are racing to restore full service but no completion timeline has been given and major infrastructure upgrades are not expected before 2027.
