66506 Crewe Regeneration passes Grove on 25 November 2021 with the 4L36 07:39 Wentloog to Felixstowe North freightliner. Although booked to run along the up relief line and stop briefly at Wantage Road, this was on the main, and would also miss out its stop at Milton, therefore getting to Didcot 21 minutes ahead of time.
