Apparently the danish state rail's solution to potential IT problems during the DST changeover is to just... stop all trains for an hour???

@charli the really difficult part is the other changeover when they have to run the trains twice as fast for an hour u_u

@charli
Easy and sensible solution.

In the USA, the changeover is always scheduled for 0200 on Sunday morning, because we're all supposed to not be doing anything then…

charli xyx @charli@amazonawaws.com

@RealGene Same here, fwiw! So the impact is quite limited, but talk about rubbing salt in the wounds of people who are already sitting in a train at an ungodly hour

timorl @timorl@social.wuatek.is

I think this is a pretty standard solution, Poland does the same.

Quite ridiculous, but DST is ridiculous as a concept so what can you expect.

@timorl the world truly runs on great software

timorl @timorl@social.wuatek.is

Hm~, I’m not sure software is to blame, rather than just problems with timetables in general. I tried finding something more concrete, like descriptions how trains dealt with this historically, but I only found that this is apparently the most common way to solve the problem all around the world nowadays, and no useful historical documents (search is so broken x<).

And now I discovered the closest rail library to me is a major city over (so not in the closest one), and their online catalogue only returns one maybe relevant result, in French, and it’s not on scihub.

timorl @timorl@social.wuatek.is

Wait, I’m being silly, this is fedi, surely someone knows, so #AskFedi:

Do trains stop due to DST because of software reasons, timetable reasons, or something even weirder?

Peter Krefting @nafmo@vivaldi.net

@timorl @charli AFAIK, yes. If they only have an arrival time (night trains not letting people on), they could probably arrive early, but that might upset the schedules if other trains?

(Found an article from 2025 confirming this for Finland - www.vr.fi/sv/aktuellt/2025/10/17/vintertiden-boerjar-foeraendringar-i-tidtabeller-2025 )

timorl @timorl@social.wuatek.is

That article only says this happens, not what the reasons are, right? Or is my translation software misleading me?

charli xyx @charli@amazonawaws.com

@timorl Huh, i see! Interesting, thanks for the info

@fugi@amazonawaws.com

@timorl couldn't they just do the timetables in UTC or some other fixed reference time, and display the times in the current local time zone where it isn't relevant?

timorl @timorl@social.wuatek.is

Heheh, I think you rediscovered the Soviet solution to the problem. All trains went by Moscow time in the USSR.

i wonder if they also just break the laws of physics in the spring

@charli This is a joke, right?

RIGHT?

(Please say this is a joke...)

@hannah I'm afraid not

I can't find any articles in English but hopefully you can translate it

Lili @Lili@donotsta.re

@hannah @charli that's not even exclusively a Danish thing, the same happens in Poland

Hannah (3.6 roentgen version ☢ ) @hannah@moonserver.yorha.nexus

@Lili @charli Well....

(Did genuinely not know about that. And it just sounds... like a shitpost. No offense.)

@charli in the UK, we don't stop the trains, but network rail have to turn off the live train movements mainframe (that's used for tracking the running performance of trains)
