DRS 37605 approaches Charlbury at some considerable speed with the 1Z14 09:45 Derby Railway Technical Centre to Worcester Shrub Hill (via Oxford) Ultrasonic Test Train on 11 September 2006, with classmate 37602 on the rear. The Cotswold Line possesses several long sections of single track, this 14 mile section from Ascott-under-Wychwood to Wolvercote Junction is particularly inconvenient when there is any late running. From a photographic point of view however, it can be a bonus, as I was able to easily get this picture, after seeing the train earlier at Shipton, as it was held at Ascott-under-Wychwood for the 13:25 Oxford to Worcester Shrub Hill to clear the section.
