47580 County of Essex heads north past Horfield on 13 March 1989 with Class 127 DPU 915 (55975 & 55985) in tow. Although clearly formerly a Stratford loco, with appropriate name and 'Cockney Sparrow' depot logo, 47580 had in fact just been transferred to Bristol Bath Road, and so is on its home patch here. The DPU had been converted from a four car Class 127 DMU in 1985, but did not have a long life in its new role, being withdrawn just two months after this picture was taken.
