The 1992 summer timetable was the last with through running between London Euston and Blackpool, in which class 47s dragged WCML mark III sets complete with DVT west of Preston. I made some effort to capture some of the final workings. This is Singleton Box on 24th September 1992, with 47825 'Thomas Telford' piling on the power and heading for Preston. This loco would subsequently be rebuilt as 57601. The 'box lasted until 1997.
