Icicle (appropriately)

I took my little advent addition out with me today - I was sure I would find a photo opportunity. But when I arrived at the place I was visiting I was politely asked to sign a confidentiality agreement and not to take any photographs. Then on the cold wet (icicle appropriate) journey home with multiple delays and extra changes of very overcrowded trains, a journey which should have taken 2 hours taking 4 1/2 I nearly forgot entirely until I spotted this angle.
