I think high speed rail has to be aerodynamically competent.

Atmospheric measurements (click here) from an aircraft can be influenced by airflow distortion from the aircraft itself. Movement of air around the aircraft fuselage can impact not only flow speed and direction, but also the concentrations of various constituents being measured. In particular, distortion of certain sizes of particles can generate errors that are larger than those inherent in the sensor measurement itself....

And I think there should be remote climate information available as well.

We know for a fact that heat causes problems with infrastructure competency. There should be remote sensors providing information to engineers and inspection personnel to prompt inspection of the rails. During the high temperatures in the USA there were rail services effected because of warping. That is a fact. 

Understanding the rails themselves and knowing when trouble can occur is all part of it.
