Derby ultrasonic

I did plan to go on a canal walk today but the rain put paid to that, no instead i needed to do something outdoors but under shelter so went to Derby instead to take some photographs. Derby is the home of the railway's research and test division so i saw 2 test trains, both ultrasonic test trains though nothing else out of the ordinary. The lighting wasn't that good but some of the photos arn't bad. You can see my photos here and judge for yourself!
