UK Rail Leasing's 56081 looks superb as it rounds the curve near North Lee on 9 July 2015 with the 6Z57 10:16 Calvert to Willesden Euro Terminal spoil empties. The loco is on hire to DCR, and has become a reliable performer on this working. This train had actually left Calvert nearly half an hour early, but that made no difference, as due to pathing constraints on this single track line between Aylesbury and Princes Risborough, it had to wait for the passage of the 2P37 10:33 Aylesbury to Princes Risborough DMU, before it could continue south.
