Was just about to leave work Sunday night when word of this came in. Unfortunately we were armed only with our mobiles (as were many drivers and guards who just happened to be in the vacinity ). The unit involved was HC-450545, and was at the London end of a 12 coach formation. The buffers were more-or-less fully compressed. The derailed bogie was on the 11th coach (second up from the concourse). As you might just be able to tell the p-way was badly damaged and the conductor rail ripped from it's insulators.
