The former Chiltern Railways bubble cars made their final mainline journey on 13 October 2017, when they worked the 5T01 08:08 Aylesbury to Tyseley ECS. 55020 (121020) & 55034 (121034) are seen here passing Blackthorn in the gloom. I had chosen this location as the small gap between the two bridges ideally suits this short train, but more importantly because it would easily allow another picture, as the train was booked to recess at Bicester for nearly an hour. The two vintage units, which have had a considerable amount of money spent on them in order to conform to modern mainline standards, are now destined for a new life in preservation.
