Hello Mr Chips,
Apologies for the delay as I could not post the images successfully, and had to meet up with my daughter for help in forwarding the relevant photos.
On the day, I proceeded onto Gliddon Rd from Palliser Rd where it met Margravine Gdns, entering the box slowly when I saw the vehicles ahead moving along. I don't recall getting trapped within - which is what the LA is alleging. I certainly was not blocking the path of any vehicles.
Also included is a photo of the junction box that is longer/wider than the road leading to that point - which I hope will help.
Enclosed are the PCN images, photo of location, and a Google image of the site:

Box junction:
https://imgpile.com/p/oDaucGJHammersmith appears to have set up many box junctions in multiple spots, resulting in traffic being mostly backed up, at busy times as nobody can move for fear of getting trapped in the hatched area.
For example, just today mine was the first vehicle in a queue of cars at a crossroad with a box junction, but could not join the traffic until after the lights had changed five times (stationary for over 30 minutes), due to the long tailbacks on the main road preventing cars from proceeding further.
Look forward to hearing from you, and hope the images help to sort out my circumstances.
Thank you.
