Seems the fire alarm has gone off in the box. Box evacuated and all trains at a stand!
If the box is closed can we pass the signals at danger...

Is there an interface between the fire alarm and the signal panels to automatically switch all signals to danger or does the signalman have to either individually switch them to danger or press an "all stop" type button?
Doesn't it cover Norwich too? Some of the EMT services were delayed by the incident.How far does the Colchester PSB stretch? IIRC, is it the GEML from Witham to Manningtree and the Sudbury, Braintree, CET, Walton and Clacton branches?

Normal design requirements for any form of Railway Control centre is that the operating floor/area is contained within a 2 hour fire resistant block. Don't know specifically about Colchester, but if it is of standard design why was it necessary to evacuate so soon?

Pretty sure the 2-hour fire resistance is to protect the equipment, rather than the people.Normal design requirements for any form of Railway Control centre is that the operating floor/area is contained within a 2 hour fire resistant block.

Would they need to set everything to Red? All the routes that had already been set would be clear of any danger. Trains would keep going, past greens and yellows, until the eventually come to a red.
Wouldn't the protecting signal be at danger since the crossing wasn't proved clear?What if something happened up the line that would need the signaller to stop that train that has a good run of greens?
"The train hit the car that had broken down on the automatic crossing, despite the car driver's best efforts to contact the signalman."
The overall probability of a fire goes down, but at the same time the impact goes up - so swings and roundabouts really.Surely this another reason why putting everything into a regional ROC is a bad idea, whereas you could in the past "lockout" a box and just have long sections.
