168005 heads into the setting sun at Overthorpe on 16 June 1999, as it passes underneath the M40 motorway with the 19:15 Marylebone to Birmingham Snow Hill Chiltern Railways service. At this time this unit was less than a year old, and was the last of the original batch of five Class 168/0s. The subsequent Class 168/1s, 168/2s, and much later 168/3 conversions had yet to be delivered.
