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.

That's what happens when you ignore critical infrastructure for three decades.

Of course, if the government were to correct the mistakes of the past, it would get worse for another decade. The necessary repairs would cause a lot more delays, and voters would then say "Were giving them so much extra money, and it gets worse? Unacceptable!". So I fear we'll continue to have these problems forever.

It's interesting how software systems and these large systems always have the same problem. Software failures are described by the engineers as being caused by "not enough maintenance and now the code needs to be refactored" and these real world systems are always caused by "not enough funding for preventative maintenance". It's a curious case that these issues are rarely caused by actions in the present but primarily by actions (and often other actors) in the past.

Presumably, we too shall be the villains to the people of 2050 as they shall, in turn, be the morons who built this stupid fucking system in this dumbass way instead of just designing it correctly and keeping it up to date over the years to the people of 2080. One thing I must consider doing is calling any fellow coworker an idiot pre-emptively since that way it's like I'm living 25 years in the future.

Your chart shows close to €200 spent by Deutschland per capita in 2024, before the abovementioned spending splurge (about €30/person/year). (The numbers 477 and 115 never appear in your source.)

€230 in Berlin purchases about as much as €371 of CHF in Zürich [1]. So no, I’m not seeing evidence Germany needs to further 3x capital expenditure to unfuck its system, and that’s before observing it spends more than Italy per capita, and Italy’s intercity rail is fantastic.

The number €115 is in the second chart as the per capita German expenditure on rail infrastructure in 2023. I don't see €477, but it's pretty close to the €480 figure for Switzerland in 2024. My guess is they saw an old version of the page when the first chart had numbers for 2023 and have kept using it without noticing the update.

Though I think they are not spending it sustainably. There is one train line and one lightrail line between my city and the next big city. They want to do things to the train line, blocking it for half a friggin year, and they make that announcement as if they do not give a damn about anyone, who relies on that line. Everyone will have to squeeze into the lightrail trains, which take longer. Often whole carriages are mephitic and unusable, when certain people have made them their temporary homes.

If things were done with an eye to the future, we would see things like extra lines, so that when things need to be renewed/maintained train service is not completely and utterly fucked for half a year for thousands of people, who want or need to take the train for daily commute. It is in my eyes utterly ridiculous, that we rely on a single track and are fucked, when literally anything at all needs to be done. Instant 100% train service disruption. This is Deutsche Bahn reliability.

Of course that would cost more ... It's cost accumulated by decades of neglect, and now they don't want to spend that money on the citizen, but rather pay biiiig juicy bonuses for management levels at Deutsche Bahn. Predatory capitalism at its best.

And that's not all. Their software and app sucks ass too.

eqvinox 3 hours ago
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 magic numbers they wanted before the maintenance debt came rearing its ugly head and now everything is royally screwed. And because it's a private company, there's a whole bunch of barriers limiting how much they can even subsidize the thing at this point.

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.)

Well, the EU insists that track & train operations are separate. (ironically the UK _is_ combining passenger operations and track somewhat back together, which is only possible because of brexit).

The bigger issue tbh is the enormous cost inflation in civil engineering in general. This seems to be a problem everywhere. There's no doubt some of this is caused by material cost increases, labour shortages etc, but I'd say the huge amounts of regulation added over the years is really a core driver of this.

“About 72 per cent of Deutsche Bahn’s intercity trains arrived within 10 minutes of their scheduled arrival time in the year to January 2025, compared with 78 per cent of British long-distance trains, according to the FT analysis.

Any interaction with the German rail network is also one of the biggest factors affecting the punctuality of long-distance rail travel in Central Europe” [1].

The UK's railway network was only privately owned from 1994 to 2002 though, everything after that is already under the umbrella of re-nationalisation, which didn't go super well either (my knowledge about that is rather vague). Not sure how useful 2025 numbers are in this context.

[ed.: to be clear - AFAIK they are in the same state currently, private company but 100% government owned. But there's a huge distinction in that the UK has made the decision to move back in the direction of nationalisation. In Germany, some people still pretend this is somehow fine and just needs to get cleaned up before the privatization can continue.]

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.

Governments can be just as bad at infrastructure investments.

That being said, I get the sense it's a German cultural problem. I used to travel to Germany quite frequently and was always surprised at the poor quality of much of the infrastructure, including private. The cell phone networks and internet speeds were all awful. As recently as 6 years ago my phone dropped to edge as soon as I left the city and within the major cities I had terrible performance. I'm not kidding when I say that I often had near dialup speeds, despite having full LTE bars. Maybe this has improved since.

As for rail, for Europe, the rail lines should probably be run as a cooperative with the rail companies paying dues.

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.

phatfish 2 hours ago
Everything about UK rail is custom (apart from the gauge). Apparently it's one of the (many) reasons HS2 is such a mess.

They were trying to run trains faster than typical continental high speed lines, which meant custom design work that needs loads of additional testing and certification. Rather than just use the Spanish or French high speed designs.

dcel 43 minutes ago
Max line speed of HS2 is 360km/h, with provision for 400 in some sections in future. This is entirely in line with many other modern HS lines. China’s been running regular 360km/h services for years.

This is a project with a 200+ year shelf life. Designing to 300 or less would have been short sighted, and many of the changes to accommodate such high speeds actually reduce costs in the long term (slab track, headroom to catch up delayed services, ability for one trainset to operate more services per day etc).

The cost overruns of HS2 are primarily from plain old poor project management, complex planning law and constant political meddling, not engineering decisions.

That seems like a fail-safe interpretation of communication: if there is no communication, stop the train. But that's a special case. GSM-R is much more than line authorities.

>GSM-R is a secure platform for voice and data communication between railway operational staff, including drivers, dispatchers, shunting team members, train engineers, and station controllers.

Designing the communication network itself in such a way that the entire thing can apparently fail, doesn't sound "fail-safe" to me. (Though its failure may trigger fail-safes in higher-level systems.) In particular, some functions may require communications to be "safe"; e.g., emergency personnel not being able to communicate is not "safe".

But perhaps this is being overstated in the vague reporting, and it's only a regional failure.
