You can but the track has to be built for it. Japan has stations that are passed at 320km/h (200mph). You need minimum four tracks (two platforms, two passing) and curves/gradients suitable for the speed, along with noise mitigations as necessary.
If you’re trying to re-use tracks and stations built in the 1800s that’s possibly less feasible.






Road design is part of it but improving road design only improves ‘reasonable’ drivers, and things like chicanes, lane narrowing, and speed bumps cause issues for larger commercial vehicles like buses.
Persistent asshole drivers will still drive drunk or drive dementia, run red lights, or go three times the speed a road is built for.
“the systems and environments we place people in” is not just the road. It’s the licensing regime, the society that makes having a car necessary even if you can’t drive safely or afford to maintain it, and that doesn’t mandate effective ongoing training.
