IMHO there's an urgent need for an indepedent review of the operation of ECML. It's obviously that systemic failure in control and operations is the root cause of these total collapses in response to every hiccup.
Hmm; there will be reviews both by Network Rail and East Coast as is always the case after such major problems.
As to systemic failures.........; if you've ever been on the ground when such incidents happen, and remember we are talking incidents in the several that occurred with fires, failures etc, then no, it doesn't matter what advance plans you have there are occasions when matters build to the point where it is almost impossible to deal with.
I can't speak for EC now, but I still have bad memories from a day when on duty at PBO with ICEC and we had wires down across Holme Fen, followed by wires down between PBO and GRA! We had contingency plans in place with local coach operators, BUT, this all happened at school time in the afternoon so no spare coaches to be had for at least two hours.
On top of that we had Central Trains running normally and disgorging pax regularly who wanted to go north/south and then later WAGN were coaching up from Huntingdon but wouldn't allow THEIR coaches to carry on to GRA to connect with trains that were being turned back.
It was utter chaos for many hours, and well into the evening before we cleared everyone with some having to stay in the Great Northern Hotel overnight, which by the way had already opened up its function room to provide somewhere for pax to go whilst they waited.
Whilst all this was going on, we were also planning with the coach operators to provide coaches the following morning to allow our London commuters to get to work.
