The Great Northern Railway recognised the value of 'mixed traffic' locomotives in the 19th century. Lindsay says that seventy five locos of this class were built. One source says that a total of 117 Class 18 locos were built. The Great Northern Railway Society says that 153 were built. The different sources seem to agree that fifty of the class were out-sourced from locomotive builders, the remainder were built in-house at the Great Northern's Doncaster works
