American here. We know exactly why we can’t have this.

• No prior experience in building and operating high speed rail.

• Track standards must be much higher.

• Track must be completely secure from people and animals, and geology. This means high fences and shallow cuttings set far back from the running lines.

• The line can only be crossed by bridges or tunnels. No level crossings.

• Long distances pose issues in crew turnaround.

• Track must be as straight and flat as possible. North America has space, but also has geography.

• Reliable catenary power supply.

Especially considering all of your major cities are in a straight line.
