No, it's not.

The Talgo XXI does 159mph, and the Russian TEP80 did over 168mph in a test run, which is even preserved on video: http://www.youtube.com/watch?v=wwYXjxXFha0 http://www.youtube.com/watch?v=DWDdNe_zx5A

Interesting, however all of the references I could find still quote the HST125 as the official record holder. I expect due to one technicality or another.
