It's fascinating watching everyone poo poo a collective brick when rail is still probably a couple orders of magnitude safer per passenger mile.

It's how they got the dutch/belgian contract. They said they could make a 250kph system for cheaper than siemens and alstom could make a 220kph, having never produced a high speed setup on their own before.

This is all after the DSB debacle got well underway, so there's really no excuse.

I love the thought of people with dubious driving ed barreling next to the unprotected bike lane. They drive 7% of kilometers but are responsible for a third of cyclist fatalities.

In the UK foreign drivers also kept killing people on the highway cause they couldn't/wouldn't check the right side blind spot.

Show me a way to slow down over a mile of 80+ ton train cars faster, that is actually feasible in the real world.
I'm not saying they're purposefully under engineered, it's just shocking how little influence they have on their speed.

On the flipmode, how are (modern) trains in the Netherlands so drat quiet? I've been on Acela, Amtrak Silver service, and UK West Coast and they were all loud or at least not quiet, while on every Dutch train I felt self-conscious about the tack-tack-tack noise the iPhone keyboard made before I muted it.
All the trains you've been on are shitshows basically. If want to experience good comfy trains your options are basically france (only the high speed stuff, though some of the regional lines have slowly started improving their stock), germany and switzerland, IME. Their might be others, but I haven't experienced them first hand. Once the rail is actually maintained and the cars have proper suspension it's p easy to make it a pleasant experience.

To have spring-operated brakes that require air pressure to release, you'd need each car to have an engine, compressor, battery and fuel, to make them reasonable to move around on a moment's notice. They also need the ability to sit in the same spot, in every kind of weather, full shade or full sun, for years on a storage track, and then be ready to go with next to no maintenance, so a lot of ancillary braking methods won't be both cost-effective and feasible.
Yes, better have a runaway every couple years.

Nationalize all passenger rail
It's not just the nationalizing, it needs to be independent. The tech team on that project advised against giving them even the time of day, but they went ahead because *must buy lowest bidder guysssss* and here we are.
I'm so glad our regulations specify best value instead of lowest price. It makes it trivially easy to dismiss lowball shitbag bids.
