Germany’s national rail operator, Deutsche Bahn, said a scheduled technical update caused a major disruption in its digital railway radio system, bringing train services across the country to a temporary standstill. The outage affected long-distance, regional and some local transport services, making it one of the most significant rail disruptions in recent years.

According to Deutsche Bahn, the issue originated during the replacement of a technical component in the GSM-R communication system, which is used to connect train drivers with traffic control centres. Train operations were suspended for around two hours on Tuesday before services gradually resumed overnight and into Wednesday.

Authorities stated there is currently no evidence of sabotage or external interference. The incident comes amid growing concerns about the vulnerability of Germany’s critical infrastructure and adds to ongoing criticism of Deutsche Bahn over delays, cancellations and aging infrastructure. The company said investigations into the exact cause are continuing while rail services have largely returned to normal.
