56073 approaches Wolvercote Junction on 7 April 1988 with the 6M55 17:30 Didcot Power Station to Three Spires Junction MGR empties. This was a bit of a surprise, as the Three Spires workings were usually Class 58 hauled by this date. 56073 was one of the two class members that were fitted with experimental remote control slow speed equipment, and consequently had roof mounted flashing lights. This was not a success, and the equipment was removed in the early 1980s.
