66589 runs along the up relief line at Challow on 28 November 2017 with the 4L31 09:03 Bristol to Felixstowe North freightliner. Most of my favourite photographic location on the Great Western Mainline have been completely ruined by the electfrication masts, but this one still offers a number of different vantage points, albeit with the masts still disfiguring the view.
