Can you see the cut cable?! SIREN TEST - Carstairs Junction

I met two other siren enthusiasts today (wow! ...have I started something here?)
Anyway, this was NOT one of my best attempts! Here is how the video is 'not up to my usual standards'...
1) CAMERA STAND - with 5 mins to go, attempted to set up my usual two camera positions for multicamera view. With camera zoomed in so far, one slight nudge drastically affects the position! Couldn't get it right and aborted due to lack of time!
2) SD CARD - with 30 SECONDS to go, pressed record and camera flashed "NO MEMORY CARD". OMG, I had left SD card in my laptop in the car! Almost a disaster! Quickly dashed back to car, inserted into camera, pressed record with seconds left.
3) DRIP ON LENS - GRRR wish I'd noticed this whilst filming, but it does go away in the end!
4) Both shutters jammed, horrible muffled noise.

Here is the shutter video. See INSIDE the shutter mechanism when we get to examine a siren being decommissioned:

By the way, I met up with @al66class59 and @ewanmarshall2010 for those who are asking!
