Didn't leave work until after 8pm and as my train was diverted, I had to head up to Liverpool Street station...
I've taken this type of shot before - And to be honest, much better than this, but I wasn't really in the mindset to take photos so just clicked off a couple of shots and jumped on my train...
Andy see my shot from last week (8 April) we literally have identical shots! Although mine was taken at lunchtime. I assume you are balancing you camera on the sign overhanging the railing as well?!?
