Unusual traction for the 4V22 16:03 Longbridge to Swindon Rover car body panel empties on 30 April 1999. 58020 Doncaster Works is pictured passing Spetchley, deputising for the more usual Class 66. Around this time there were other instances of different classes appearing on this train, including pairs of 37s. I do not remember much variety before the coming of the 66s, when Class 47s had a virtual monopoly. You can draw your own conclusion about what that means!
