Having departed from Claydon Loop a little early, 6Z91 is still running early as it approaches Islip station at 12:07, though actually almost 24 hours late! 56312 had failed at Claydon the previous day and 56301 was sent to rescue the train and engine. 56312 was later towed to Washwood Heath by DCR's 31601.
