Germany’s national rail operator, Deutsche Bahn, halts trains across the country due to a problem with a railway communication system, bringing service to a standstill and leaving some passengers stranded. Multiple outlets report that the disruption is linked to an IT or communications issue affecting network operations. Deutsche Bahn holds trains at stations during the outage, which occurs late Tuesday evening. One report specifies that the problem involves the GSM-R digital radio communications system used for internal railway communication. Deutsche Bahn initially reports the issue and later provides updates as the situation develops. According to PBS NewsHour, shortly before 1 a.m.—nearly 2 1/2 hours after Deutsche Bahn first reported the outage—the operator says the problem is resolved and services resume “step by step.” Across the reports, the common account is that the nationwide communication-system outage triggers widespread train delays and cancellations, followed by a gradual restart of operations once the technical problem is addressed.
