closed when in transit

I like this shade of black and texture so I took the picture. It is a tap or release valve on a train carriage that carries some kind of chemical. The instruction to "keep closed while in transit" is likely because air rushing past an open valve on an empty tank would likely cause a vacuum to increase and decrease inside in relation to the speed of the train. Apart from being noisy (like a church organ) it might also expel chemical residue. Well that is my hypothesis anyway.

On the lead up to remembrance day I thought I would post this shot I took in the Imperial War Museum (Duxford) last year.

So today James and I were towing the boat through the back streets of Hamilton on the way to winter storage, and all of a sudden lots of police cars and police motorcycles came rushing from the opposite direction. So of course I grabbed my camera and fired off a few shots – and what would you know – Prince Charles!
