ok so i'm pulling together a retrospective for 2023, and while doing so i found this:
>https://www.networkrailmediacentre.co.uk/news/end-of-an-era-for-birmingham-new-streets-iconic-signal-box>https://my.matterport.com/show/?m=a7aSN6y5sDH...a few boffins from Birmingham Uni scanned the inside of the Birmingham New Street power signalling box using LIDAR, after it was made redundant last year, and turned the results into a 3d VR doodad thing you can wander around. I'm honestly surprised at how small it is, for a nerve centre - a desk, a whole heap of early Cold War tech, and not much else. Still, this was absolutely state-of-the-art at the time.
The building itself is listed, so they're unable to demolish it, but they're apparently going to turn it into a signallers' training centre - which, I suppose, is the reason they thought to scan and preserve the interior while it's still possible.
