Picture(s) of the week- 18th March 2013

Having not ventured out to the railways all month the promise of a class 31 working some of my more local lines was a temptation too good to miss- and on an evening I had no prior plans. 
31465 was turned out on UTU4- a Network Rail ultrasonic test train which made several trips between Waterloo and Clapham Junction before heading further into the SWT suburbs.
The train is seen here making it's unusual appearance at Waterloo.
