The U.S. doesn't currently have any operating high-speed rail lines.

The headline appears to clash hard with the actual text and even more so with reality…
To Urban Sky's point, this is really a 'story' based on a quote of a former U.S. Transportation Secretary who aspirationally said something like ' If only we can get one of these HSR projects done, I think it will start a snowball effect'.
Only thing. None of the projects that are underway, most notably California HSR, are anywhere near complete.
Optimistically, maybe they'll have something going by the early 2030s (the current objective is a time range of 2030-2033 for phase 1); but they are not pacing in line w/that objective. There is also a material risk that Trump may pull existing committed federal dollars.

Meanwhile, only that and Brightline West (Vegas to So. Cal) are really past the fantasy stage. The latter may, aspirationally, reach operation in 2028; but that is a very fingers crossed timeline, and also assumes that certain supports will remain in place.

Illinois and Texas both have projects in the on again/off again, lets plan this some more phases..... Something may well come of either.........but we're not close to breaking ground, let alone operation. Indeed Chicago - St. Louis is only at pre-planning. (feasibility).
The Texas project is further along, but is looking at 8 years of construction, which can't start before next year; and given opposition in the State Legislature...... we shall see.

Suffice to say, I wish the U.S. well in these various endeavours. I think the idea is sound, though as with CaHSR, some of the details are problematic. Still, great if it moves ahead, but a near-term breakthrough seems improbable.
