@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"])
