And even that is not entirely true. The TGV can only run this fast because it runs on tracks where only the TGV is allowed. The rail bed is even not that great, that's why only some ICEs are allowed on TGV routes, because they need a special deflector which is more robust to tolerate the stones which are thrown up in the air when the train drives over it. I think they took this in consideration when they designed the latest iteration of the ICE. |

If https://en.wikipedia.org/wiki/High-speed_rail_in_France is to be believed, the high speed lines for TGV are primarily but not exclusively used for TGV:
"LGVs are reserved primarily for TGVs. One reason for this is that line capacity is sharply reduced when trains of differing speeds are mixed, ..." "Some stretches of less-used LGV are routinely mixed-traffic, such as the Tours branch ..." "Outside France, LGV-type lines often carry non-TGV intercity traffic, often as a requirement of the initial funding commitments."
I'm also not so sure about the quality of the rail bed:
"Track alignment is more precise than on normal railway lines, and ballast is in a deeper-than-normal profile, resulting in increased load-bearing capacity and track stability. "
