Kings Cross power signalbox closes

kxpsbcloses 1 - Kings Cross power signalbox closes

Early this morning the very last train was signalled out of Kings Cross under the current arrangement that had existed since the time the station area and throat were remodelled in the 1970s. With this step forward in the East Coast Upgrade the station will open with a completely new look from Monday 26th April 2021 to the station’s east side of rail operations – whilst the west side of the station in turn gets closed and work begins to modify the layout and install new signals and infrastructure. The station will in future be controlled from York ROC, although the line will be controlled as far as Peterborough for the moment – where its power signal box retains line control northwards until the envisaged 2024 handover date when that control is too taken over by York ROC.

Great view of the King’s Cross #EastCoastUpgrade site! The power signalbox can be easily seen, its 2006 extension quite prominent. The new Google headquarters (at right) looks much bigger than the station itself! Source: Twitter

If those two earlier pictures do not satisfy one’s thirst for the latest railway signals on offer, how about this one eh? These are Dorman Non Standard Route Indicators, or rather what’s known as a ‘Miniature Tunnel Signal with Proceed on Sight Authority (PoSA) Aspect.’ (see Dorman’s website.) This is sited in the Gasworks middle (or No.1) tunnel. There are other variations of this type of signal too, for example YA1045 in the eastern Gasworks tunnel. Picture source: Twitter

Nice view of the power signal box in its final week. Note the panel and how half of King’s Cross station is already gone. Just platforms seven to eleven are still signalled. The others will be controlled from York instead and these platforms here will follow in due course. Source Twitter
