German rail company Deutsche Bahn(DB) resumed train services after a tech outage halted all trains nationwide for a little more than two hours late Tuesday night.

DB said a fault took place in the so-called Global System ⁠for ​Mobile ​Communication for Railways (GSM-R) system, which is used to link train operators and control centers on the railway network.

Shortly after midnight, the situation was stabilized, but disruptions in the network were expected into Wednesday morning.

"A disruption of this kind has never occurred before due to the high security measures in railway operations," Deutsche Bahn said in a statement on Wednesday.

Regional and suburban rail operators run by Deutsche Bahn also said on X that services were gradually restarting, but warned that major delays and cancellations were likely to persist into Wednesday morning.
