> As for freight, the US actually moves a significantly greater portion of its freight by rail than Europe does. Rail has around 40% modal share for freight in the US vs only 17% in Europe. One reason for this is that in Europe many line

There's enough tolerance that you can run 1520mm rolling stock on 1524mm track and vice versa.

Oh, right you are! I stand corrected. Though I have to say, that's not exactly the best UI. Not sure what the solution is OTOH, it's certainly not useful to clutter up the map when zoomed out either.

That's only the main tracks. There's a huge amount not seen on that map.

In 1886 the USA switched the rail gauge of the southern states to standard gauge. Most of the work was done over two days. http://southern.railfan.net/ties/1966/66-8/gauge.html Obviously doing this today woul

Not incidentally, 1524mm is exactly 5 feet. Which was the rail gauge widely used in the southern US states. The Russian tsar hired someone who had been building railroads in the US south to design his railroad, and here we are. The 1520mm w

The difference is so marginal it doesn't matter, and is certainly not worth the cost. Both the heaviest cargo trains and the fastest passenger trains (ignoring monorails, maglevs etc., just normal style trains running on two steel rail

As mentioned, not really an issue on a modern system. But in any case, you could just read, say, 1K from /dev/urandom into a buffer and then keep resending that buffer over and over again?

For a docker-compose replacement you should probably look at the 'podman kube' support. That supports a subset of the kubernetes API that roughly matches the docker-compose features. Then for deployment to a Kubernetes cluster you
