With the sad remains of the disused Didcot Power Station dominating the background, 66723 Chinook approaches Culham on 28 March 2018 with the 6M40 11:56 Westbury to Stud Farm ballast empties. Note that the bodyside number has been altered to read ZA723, in recognition of the RAF's Boeing CH-47 Chinook helicopters, which also explains the bodyside graphic.
