56056 arrives at Princes Risborough on 15 May 1993 with the late running 6A70 01:30 Northolt to Calvert Binliner. This is the point where the up and down lines merge together again, after separating at Saunderton. 56056 marks a slight change in the front end design of the class, with the removal of the protruding lip above the buffer beam, and a larger, square horn grille. Note the Westbury 'White Horse' depot plaque.
