The BR class 22 type of diesel hydraulic locomotives was confined to the Western Region but MIAC has been unable to locate any photographs of the class actually in use in Worcestershire. The 58 locomotives of class 22 were built by North British from 1959 onwards and fitted with NBL or MAN engines and Voith-NBL transmissions. They were of the mixed duty 'type 2' classification.
Phil Bullock has provided three observation notes that confirm that a few of the class were active in the county for short periods (the actual dates not yet confirmed):
No.D6331 was seen on a permanent way train at Abbotswood where it came off the Worcester line having presumably either brought the train from Newland or came on at Worcester. It came across the junction onto the down main and then - clonk clonk bang! It expired with its train across the junction probably the strain of coming so far north! It was a locomotive regularly seen at Gloucester so perhaps they were desperate that day.
No.D6342 on an inspection saloon at Shrub Hill one lunch time - before it was incarcerated on shed!
And another class member running light - southbound - at Spetchley, the number escapes him but presumably got at least as far north as Bromsgrove.
After withdrawal a few examples made their way to Worcester for storage.
