67028 passes Grove in the gathering darkness on 14 November 2019 with the 5Q96 14:49 Didcot Parkway to Swindon Transfer overhead line test train. 90035 is doing the actual testing. The 1A21 14:30 Bristol Temple Meads to Paddington IET can just be seen disappearing into the distance, luckily getting out of the way just in time!
