Fascinating how such a simple solution is so timelessly effective. A "framework" going two centuries strong.

For the majority of track, this is fine. High speed track uses ballastless track because at high speeds, making gravel fly is very damaging. (It also tends to be noisier and less smooth.) https://en.wikipedia.org/wiki/Ballastless_track https://en.wikipedia.org/wiki/Ballastless_track

  Appreciate the link, could you edit the `.m` out of the URL so it doesn’t point us all to the mobile version? Ta. > Therefore, ballastless tracks must be concreted within a tolerance of 0.5 millimetres Wow.

    It would be even better if Wikipedia themselves fixed the problem. Here's how I would like to see it: There is only one URL per article, not a desktop URL versus m-dot URL. When you land on the page, if you have no cookie, then Wikipedia autodetects based on your size/orientation/device and gives you a desktop or mobile layout. If you choose to override the presentation, a cookie will be set, and all future visits will use your preferred layout. Personally, I'm on desktop all the time and I am peeved by people who post "m." links because the mobile version hides some useful features.

  In France they use ballasted track for their high speed trains. Even the newest tracks. With daily operational speeds up to 320 km/h, and with some tracks rated for speeds up to 350 km/h.

    It's not impossible just has different tradeoffs. IIRC lower upfront cost but higher long-term maintenance. Also idk I just lived next to a tgv line for a few years but it's loud as a fucking jet even dug into the channels they use around residential areas.

      Noise reduction techniques sometimes channel or reflect noise instead of absorbing it, so it is only quieter for some people in some areas and louder for others.

The Romans were using crushed stone in (non-rail-) road construction more then two millennia ago, and it was an old technology then: https://acoup.blog/2023/06/02/collections-roman-roads/ https://acoup.blog/2023/06/02/collections-roman-roads/
