National Coal Board Northumberland No.9 (Stephenson & Hawthorn 7097, built 1943) stands outside Backworth Loco Shed, Eccles Colliery in June 1973.  
The loco had arrived from Burradon at the end of 1971 in a filthy condition, and had been repainted shortly afterwards.  At this time all Backworth locos were this clean.
