D6533 ( later 33115 ) still without a yellow warning panel and D6541 (later 33023 ) head a block oil tanker train through Banbury. The reason for so many people on or near the track is unknown.
The negative is dated 5/3/67, however the day before 7029 'Clun Castle' worked a railtour through Banbury so I suspect the actual date is 4/3/67.
