37607 speeds past the site of Wootton Bassett station on 8 April 2011 with the 1Q13 09:08 Bristol Temple Meads to Derby RTC Network Rail Radio Survey Train. 37611 is on the rear of the train. This was supposed to be the first of a series of pictures I would take of this train during the day, but in the event severe technical problems with 37611 saw its itinerary effectively curtailed a few miles up the line at Swindon. The junction in the background is where the Badminton 'cut off' route swings in from the right to join the original Great Western Mainline.
