It's either that or starlink, some railroads in Germany go through areas without any mobile network signal. Think about how crazy that is in 2026 when everything expects everyone to be online 24/7/365.
Well, it was a *planned* update of a central system component in their radio. That's why the restauration took only 8 hours. Their 90 min excuse is bonkers. Unplanned it would have taken much longer. Can confirm that their update planning process is abyssal. Half a year for the first simple reply. Comparable only to HP
"IT Outage: No train service nationwide. Due to a nationwide outage of the GSMR digital rail radio system, all trains are being held at stations. We are working around the clock to resolve the issue.
Our technicians are working around the clock to resolve the outage.
Please continue to check your travel connection immediately before departure using the travel information service at bahn.de, the DB Navigator app, or by calling the travel information hotline at 030/2970."
There was also a very peculiar train crash in the UK just a few days ago. A train hit a stationary train. That shouldn't really happen in this day and age. Sabotage was the first thing that came to my mind.
A planned major update to align with other countries platforms, which other countries did estimate to need 9 years for. So they did have plenty of time to test that update, as well as preparing a fast fallback, in case of not-working.
It doesn’t surprise me at all. Deutsche Bahn got so bad in the recent years that Switzerland started turning some German trains around at Basel (border) to protect its own timetable from DB delays.
The fallback for GSM-R is the normal GSM network, but according to informed guesses I've read, the handsets still need to authenticate using their GSM-R credentials (it's just normal GSM roaming), and that's failing too.
