As I've often bored everyone before said in my many many posts in this and other Wessex related threads - NR are riding their luck in Wessex with bankslips, trees and this latest type of thing, etc, etc - they've got lucky YET AGAIN with a high-speed derailment that probably didn't get messy as there was no intervening S&C and the adjacent platform may have "helped" and as MW said above the conductor "check" rail effect - (I understand 100+ insulators destroyed - small price to pay) BUT It is only a matter of time and probability before there is a serious incident in this area...............................
However, I hope the result this time won't be like the Western Route with the Route Director washing their hands resigning and someone from the DLR being employed as their replacement to "fix" it with soundbites 🙄
