66598 is clearly struggling, as it slowly toils up the gradient towards Sapperton Tunnel at Chalford on 4 July 2022 with the diverted 4L36 07:49 Wentloog to Felixstowe North freightliner. This was already running 77 minutes late, and the slow ascent of the bank only added to the delay, as well as delaying the following passenger services. Note the terrible state of the track, with the down line completely covered in uncontrolled vegetation. The bushes on both sides of the line were brushing the sides of the trains. Network Rail should be ashamed for letting it get into this condition.
