6201 'Princess Elizabeth' with 1Z79 Hellifield-Victoria passing Radwell, Bedfordshire, on the MML about 1 hour late. Glorious sunshine but too warm for steam at 25degC. Also shots of service trains during the extra hour waiting time. 5.6.2012 Visited the MML again at Oakley, Beds., in the hope of seeing 70013 'Oliver Cromwell' which failed to show. 2 shots of 43075/43045 northbound at Oakley during the futile wait.
