the French have real record-breaking HSR since the *fucking 80s*

meanwhile over 10 years after getting higher-speed 250km/h Pendolino sets, they still don't run at their designed speed in Poland

@rail_ the Pendolino runs at 200 km/h here, even though they’re capable of operating at 225 km/h. This is because after 200 km/h, the in-cab signalling system needs to change or something? So nobody wants to pay for that so now the max speed on the network (outside of Eurostar) is 200 km/h, even though trains and track are designed to handle up to 225 km/h

Jeder :neocat_googly_woozy: :neocat_flag_agender:

@yassie_j @rail_ i mean our pendolinos can't run above 160 without etcs

Jeder :neocat_googly_woozy: :neocat_flag_agender:

@yassie_j @rail_ so consider yourselves lucky that yours can

Jeder :neocat_googly_woozy: :neocat_flag_agender:

@yassie_j @rail_ hell, alstom was hellbent on certyfing them for ONLY 160 in poland

@jeder @rail_ 160………

@yassie_j @rail_ @jeder its kinda funny, the traditional UK train safety system (AWS+TPWS) is a kinda cobbled together mess, the speed limit is higher (125mph 201km/h) and the lines are very intensively worked yet the UK railways are among the very safest in Europe.

The most probable answer for how this happened IMO is “They put the Rail Accident Investigation Branch and the Air Accident Investigation Branch in the same office”

Jeder :neocat_googly_woozy: :neocat_flag_agender:

@erincandescent @yassie_j @rail_ traditional polish train safety system is even more hilarious because it's: SIFA, and another SIFA that you cancel on every signal and the max speed limit is 160km/h (though you needed a second driver for 131-160km/h for a long time, because "safety concerns" yadda yadda [there are no studies that second driver actually increases anything besides the older drivers/trade unionists {they are, uhhh, quite bad here} paycheck, but it was seen time and time again that it's quite detrimental for lowering safety, but now some want to bring it back because we had some SPADs {some of them actually didn't happen at 160km/h} and their paychecks are probably "too low"])

@jeder @yassie_j @rail_ ok that's pretty miserable but tbh nothing will ever surprise me more than Germany's "the signal is broken, ignore that it's red and proceed" signal (Zs1)

Erin 💽✨

@jeder @rail_ @yassie_j one of the rare really good German accident reports talked about how when they talked about the stated reason for existence of this signal + it's existence this to anyone from outside Germany they basically all were absolutely incredulous

@[email protected] @[email protected] @[email protected] @[email protected] France does have something kinda like it with the OEilleton on Nf signals though if I understand correctly

Erin 💽✨

@aliceif @jeder @yassie_j @rail_ at least per the english wikipedia summary, this is not installed before points though, right? only on straight mainlines?

In germany they install them at points and then crashes happen because the signaller cannot keep this many things in his head at once (and then they blame him and send him to jail…)

Jeder :neocat_googly_woozy: :neocat_flag_agender:

@erincandescent how does that keep happening on your side :neocat_googly_woozy:

@jeder i changed my default to MFM so I could do hueg emoji :neocat_3c: but Akkoma’s MFM parser gets underscores in usernames wrong

(there’s a new parser that’ll probably land next release)

Erin 💽✨

@jeder anyway I only really notice this normally when e.g. both rail_ and yassie_j show up in one thread

eta

@erincandescent @rail_ @yassie_j @jeder the UK also has this in some places though; it's called a Proceed on Sight Authority (PoSA) and is used to speed up cases where the track circuit fails

Erin 💽✨

@eta @rail_ @yassie_j @jeder do they do it past converging points?
