66536 approaches the site of Ashbury Crossing, near Shrivenham, on 20 April 2015 with the 09:57 Willesden Euro Terminal to Fairwater Yard, conveying various track plant used over the weekend for engineering work. Classmate 66507 is on the rear of the train. Whist I was out in the morning, this was not showing as having left, so I went home. However, after lunch I noticed that it had left two hours late. As this would now make a better picture, with the sun on the front, I went back out again! It had lost even more time by the time it reached Shrivenham.
