> It proves we are in fact capable of grading a railroad to support faster speeds. In one important way, it doesn't: the majority of the Brightline Orlando route runs over the pre-existing Florida East Coast Railway[1], which was re-graded to support speeds of 110mph, not higher. That's well below even the lowest bar for HSR (i.e. 125mph). [1]: https://en.wikipedia.org/wiki/Florida_East_Coast_Railway https://en.wikipedia.org/wiki/Florida_East_Coast_Railway
