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.

Very interesting, I always thought it was completely separate infrastructure by design. I wonder what they'll do once commercial GSM networks throughout Europe are shut down?

Upgrade to 4G or 5G.

Mainly Meta Services, which seem to spike, isn't it? And Google Fiber

A bit more, traderepublic, tiktok, snapchat, X, AWS, CloudFlare https://xn--allestrungen-9ib.de/en/ These could be based on different scales of numbers since it is midnight in Germany

And a football world cup game just ended.

>This special mobile communication standard is designed to make communication fail-safe Mmm, nope.

If nothing works, eveything is safe, no?

That is the point of failing safe. It would me much worse if some of the trains kept running...

In the long term, sure, but https://en.wikipedia.org/wiki/FRMCS is some way away, and I doubt they'll upgrade cab radios to 5G for the fallback path alone.

If this weren’t Deutsche Bahn, I’d say it’s a cyber attack. Given that this is Deutsche Bahn, though, it may just as well be a maintenance issue.

For context, in case people are less familiar with German politics: DB is in a misbegotten state of privatization, started in the 90ies. The government spun it out into a private company but still owns 100% of it. They were trying to pump it up so they could sell it for good money. They did that by skimping on everything including maintenance, to try and make the numbers look good. Except they never got to whatever m…

> Not sure if this is better or worse than the UK's Network Rail story, but at the end of the day the only thing that will solve this is if they re-nationalize the tracks & infrastructure. What kind of an idiot thought including that in the privatization is a good idea is beyond me. It's not like you can build a 2nd railway network in order to get free market & competition. (For comparison, imagine privatizing the entire road network, village street to Autobahn.)

If you privatize the infrastructure and trains together you can at least compare one region against another, even if they're not directly competing. Trying to operate the trains separately from the tracks was a disaster in the UK and lead pretty directly to two mass casualty incidents.

Deutsche Bahn doesn't manufacture rolling stock. They buy it from Siemens, Stadler, Talgo, Alstom etc... Edit: AFAIK, some of it - mainly high-speed trains - is designed according to DB specs and subsequently offered under a new name (and with changes) to other train companies. For example DB ICE 3 (manufactured by Siemens) / Siemens Velaro.

You can probably buy some of the older rolling stock from DB thought.

It does happen occasionally, but DB tends to run, maintain and sometimes upgrade its successful (~reliable and widely introduced) rolling stock until it falls apart or is grossly outdated (40+ years old). Rail passenger numbers are increasing, so there is no need to sell stuff to downsize.

The Flixtrain company uses 40+ years old IC (intercity) cars - they have no air conditioning and it's really loud inside with open windows, especially so in tunnels. That is the kind of stuff that DB sells.

Any HNer blocked in a DB train who can share with us the experience?

We departed around 30-45 min late from Basel sbb (in Switzerland) in a night train that goes through Germany.

They told us about the communication issues but what surprised me is that they told us that the Deutsch bahn replaced the locomotive with one of their (that was near the border I guess) so we could depart.

A truly chaotic week in Europe, alongside the UK train crash and the unprecedented heat wave.

It could be chaos on Dutch rail too the coming day. Trimmed down schedule on some of the busiest routes (due to the current heatwave). Add to that a labor union strike on Wednesday June 24 (that's today local time as I write this).

Although NL rail travelers are usually quite good at anticipating, and adjust their schedule. So might just be a quieter-than-usual day.
