I went to Tackley on 27 June 2018 primarily to photograph the 6M28 18:16 Hinksey to Bescot engineer's working, so I was not overly impressed to see this approaching! 66518 picks up speed, after inexplicably coming to a stand just a little further south, as it works what is clearly the 0M28 18:16 Hinksey to Bescot.
