That's the effect of "progress and rationalisation". I don't remember so many problems when there were proper signal boxes.

All signalling is being moved into these centres across the country, means they can all communicate with each other quicker so disruption happens less, but if something like what happened at Three Bridges today happens - then it basically googles up a region. Had it have been a big fire today, then were talking weeks of problems for the whole London - Brighton line, as this centre controls signals up to Thornton Heath !!

I don't quite understand how a fire alarm can cause that must chaos for 10s of thousands of people from before 06:00 and won't be "normal" until 14:00 ?? Something is seriously wrong with this system.

Because all the people that control the signalling system were evacuated from the building due to a fire (which apparently there was, just a minor one). Signalling was back at about 6.45 but because everything was delayed and all over the place, it takes time to recover because so many trains run in the area which was affected, no trains ran in an area between Worthing, Horsham, Thornton Heath, East Croydon, Oxted and Lewes - though it doesnt look too bad now.

Going to be one of those days today - trains suspended between Cosham/Havant and Portsmouth - person under a train at Hilsea, going to bugger up the West Coast line even more now.

That is crazy. No disaster recovery contingency plans. Single points of failure. What is this the 19th century ??

Recovery plan is to simply get trains moving again, which involves terminating them at other places or running them fast so it doesn't cock everything for the rest of the day up. This was what Southern call "Code Black" - basically meltdown, first time in about a year that's been called, everything else is usually "Code Red" which just means Major Disruption.

Had the building have been destroyed, I'd have thought another centre could probably take over, that or Ernest can get off his ARS and manually do the points HIMSELF.

indeed, its bizarre when nowadays companies try to develop strategies for infrastructure to be decentralised and distributed, the rail network has gone the other way.
