German rail service has been suspended nationwide due to a malfunction in the GSMR digital rail radio system. Deutsche Bahn confirmed all trains are being held at stations while technicians work to resolve the communication failure. The system is critical for train coordination and safety operations across the network.

The outage began after the digital radio communication system experienced a failure, leaving passengers stranded at stations across Germany. A Deutsche Bahn spokesperson said technicians are working around the clock to restore the GSMR digital rail radio system, which enables voice and data communication between trains and control centers.

SBB, Switzerland's rail service, reported only one delayed train and confirmed it is not affected by the German disruption. The Swiss operator is in contact with Deutsche Bahn to monitor the situation. This failure demonstrates how dependent modern rail networks are on digital communication infrastructure for safe operations.
