Instead of working its own train, the last run of the flyash empty wagons from Calvert returning to Willesden Euroterminal, 56091 had to rescue failed 56312 and the wagons of the previous evening's 6Z81, taking them from Claydon loop to Willesden via Oxford and the GWML. 56312 had failed at Aylesbury and the train was moved by 66547 which was stuck in Aylesbury North Loop with 6M23, the empty Cricklewood "binliner" until the following morning. The entourage approaches Islip station at 12:05 on Friday 14th June 2013. Digital Image No. GMPI16051.
