Phillippe is mistaken. The TGV broke the record on regular railroad tracks. That's not unheard of, check this out. http://www.midwesthsr.org/pdfs/M-497online.pdf
"Regular railroad track" in the TGV's case is continuous welded rail (used everywhere in railroading today) on concrete ties (used on most transit and passenger lines and some heavy freight lines) on an extra heavy ballast section (i.e. more crushed stone between ties and subgrade.)
If you wanted to build TGV track in the United States, all the materials you need are readily available; any large freight railroad will have all that stuff in stock. Well, the overhead catenary wire (that supplies electricity) is a little exotic, that'd be a special order. But the track is normal.

The new record that the tgv broke about a month ago was done on a rail using technique of air cushion. So the train is actually not touching any rail...

Steel rail, concrete ties and rubber tie plates.
