I thought the Trent Valley had been used under tests for Pendolinos at >125mph?
All stock has to be given a 10% overspeed test somewhere or other, but that would be done under special conditions, effectively no other trains ahead of the testing location. It doesn't necessarily follow from that that it can be also done safely under normal traffic conditions.
