The British Rail Class 33 also known as the BRCW Type 3 or Crompton is a class of Bo-Bo diesel locomotives ordered in 1957 and built for the Southern Region of British Railways between 1959 and 1963.

A total of 98 class 33s were built by the Birmingham Railway Carriage and Wagon Company, and they were called "Cromptons" after the Crompton Parkinson electrical equipment installed in them. [1] Like their lower-powered BRCW sisters (BR classes 26 and 27) their bodywork and cab ends were of all steel construction

The original (1957) number sequence was D6500–D6597. [2]
