When 66847 failed at Toton with an AWS fault, Colas dispatched sulzer powered collegue 47739 Sir Robin of Templecombe to assist the train forward from Toton to Radcliffe power station, then following unloading to Derby Chaddesden sidings. Few thought that the train would see a return of 47739 but the faith placed by the Colas management in their veteran locomotive was warrented as it managed dilligently with the task of taking the coal train and its former charge of 66847 back to Wolsingham on the Weardale Railway.
The pictures in the collection show the train at various points of the line from Darlington. First near North Road, then at Shildon near Locomotion, Bishop Auckland (where it is seen with the Weardale Heritage Rail service - powered by a class 33), Witton Park viaduct and finally near Witton-le-Wear.
