Overview

When James Holden took office on the Great Eastern, there were few 0-6-0T locomotives, most shunting being done by 0-4-4T and obsolete tender locomotives.

These small locomotives had 16 12-by-22-inch (419 by 559 mm) cylinders, 4-foot-0-inch (1.219 m). coupled wheels and a grate area of 12.4 sq ft (1.15 m2). They were rebuilt between 1898 and 1908.[1]

No. 8387 at March Locomotive Depot 17 July 1946.

Withdrawals started in 1936 when four (7278, 7287, 7303 and 7308) were sold to Sir Robert McAlpine and Son, the latter concern also having five on loan from late 1936 to mid-1938. Three others were sold, with No. 297 going to the Mersey Railway in 1939 as their No. 3 to work ballast trains. By the end of 1940, thirty-one had been withdrawn, and the remaining 19 locomotives continued with no further retirements until 1950. In the LNER 1944 renumbering plan, the locomotives were renumbered 8370–8388. Withdrawal restarted in 1950 and all were gone by the end of 1955.

In 1952, Three locomotives, 8370 and 8378, and 8382 were transferred to the service list as 32, 36, and 31 respectively.
