Literally!
I took far too many of that one area, probably 50 or so photos, I've never seen so much equipment crammed in such a small space, I can only imagine the amount of heat that lot would have generated. The interesting thing is there's a few modern phone lines in there, I followed one which terminated in a modern BT line box, run in a piece of CAT5e cable and it's patched into part of the old frame - all that cable coming into the place and they managed to patch in a single phone line in it's later life using the old cabling, quite amazing really. If I'd managed to find a phone handset with a plug on I would have been sorely tempted to see if it was still connected! Imagine calling someone, they wouldn't believe where you were.
