This needs to be higher. The US has the most rail in the world, at over 224,000 miles 257,000 km according to Wikipedia or 149,000 according to Statistica. Europe, by comparison, has 94,000 miles. the European Union, by comparison, has around 200,000 km recently according to Statistica. That's one country having more rail than the total of a whole continent. The original numbers came from Florida, which automatically makes them suspicious, but these ones are still pretty impressive.
The map down in the meme appears to only be Amtrak.
Oh. I found it. It was Florida rail. I'll update the numbers with more accurately sourced ones. It should be 260000 km according to Wikipedia, although statistica lists 149000km (still the largest in the world, but significantly less). I wonder if the Wikipedia number is before a bunch of rails were destroyed. Basically that would be our high score, but really the high speed rail should be the goal of which we basically have none.
Statistica also lists the European Union, so not all of Europe, at 220000 km in 1990 (and declining since then, but who isn't). Dunno where Florida rail got their numbers but I should know better to trust anything coming out of that state.
