      According to the bog-standard UIC definition, HSR requires dedicated HSL running generally at 155+mph. UIC has a second definition that does allow for upgraded conventional lines running generally at 125mph in corridors without air competition. Acela meets neither of these metrics.

      Even aside from the air competition issue, Acela’s general overall speed is not over 125mph or even 100mph due to all the slow sections. For example:
