Serco men were route learning round the Blyth and Tyne route which necessitated a trip (nearly) up to the Alcan import terminal at North Blyth. 31454 was the traction of choice and it is seen here at the NR limit at North Blyth – denoted by the small sign at track level). In the distance you can see the floodlights of the newly built Battleship Wharf coal import terminal. 18/09/08
