  • 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.
