History

The 710 class were built by the Islington Railway Workshops as a modified version of the Armstrong Whitworth built 700 class locomotives. Coal shortages after World War II saw a number converted to burn oil. All were later converted back to coal burners. The first two were withdrawn in July 1961 with the remainder replaced as 830 diesel locomotives entered service. The last was withdrawn in September 1967.[1][2]
