66599 runs along the relief line, as it approaches Banbury on 2 June 2020 with the 4O95 12:18 Leeds to Southampton Maritime freightliner. This was running five minutes late, but it cut short its booked stop at Banbury, and so was 15 minutes early as it arrived at Oxford. Missing out its booked stop at Oxford North Junction, it then passed through Oxford station over an hour early, but this early running was then checked at Reading.
