In 1985, 22 redundant Class 127 power cars ex-Bedford-St.Pancras (Bed Pan) services, including the first built, No.51591, were rebuilt to form 11 two-car parcels units and repainted into BR green livery. Vehicles were renumbered 55966-987, and formed into sets CH910 to CH920. They were fitted with roller shutter doors and were based at Chester depot. They lasted in service until withdrawal in 1989. Unit 55966, seen here at Bletchley on 29th August 1988 in the company of 55967, was converted from 'Bed-Pan' unit No.51591, and was subsequently preserved at the Midland Railway Centre upon withdrawal from BR service. ©Gordon Edgar/Railphotoprints.co.uk
