The British Rail Class 22, originally called the North British Type 2 diesel-hydraulic, was a class of diesel-hydraulic locomotives designed for the Western Region of British Railways and built by North British Locomotive Company. They were very similar in appearance to the Class 21 diesel-electrics. The Class 22 was nicknamed "Baby Warship" because of its similarity to the British Rail Class D20/2.
