in the range No. 840 through to No. 943 (though not contiguously), those built after late 1922 (from No. 2365 onwards) directly receiving their LNER number. By the Groupings of 1923, thirty-eight locomotives passed to the London and North Eastern Railway (LNER), which built thirty-two more starting with No. 2366 on 4 January 1923 and ending with Nos. 1384 and 1385 on 1 January 1924. Twenty-four of the class were rebuilt starting in the 1930s and 1940s. The original Raven-designed locomotives were designated class B16/1. Gresley rebuilt seven of the B16/1s, becoming class B16/2. Thompson, meanwhile, ordered seventeen B16/1s be rebuilt, these being designated class B16/3. Under the LNER, the B16s hardly ever left the North East. Their duties included fast freights, express passenger trains, excursions to Scarborough, and even football specials. During World War II, some of the B16s moved to the Great Central Main Line, working around Banbury and Woodford Halse After World War II, the B16s were used on their pre-war duties but were also used as far south as Peterborough, where they substituted for a failed V2 2-6-2 or a Thompson B1. The 1940s also saw the entire class receive new boilers, the last one being refitted in the late 1950s. Under the LNER renumbering scheme, of 1946, they received numbers 1400-1468. All but one of the B16s survived into BR ownership, being renumbered 61400-61468. (Nos. 61400-61409 were later renumbered 61469-61478 to give their old numbers to the last ten of Thompson's B1 Class). Withdrawals One locomotive, No. 925, was badly damaged (along with A4 4469 Sir Ralph Wedgwood) during a German air-raid on York on 29 April 1942, and was subsequently scrapped. The first official withdrawal was B16/1 No. 61474 from Selby on 20 January 1958. Given the class's age and with the Modernisation Plan already in full swing, withdrawals were rapid. The last, of any variety of the B16s, was B16/2 No. 61435, being withdrawn on 21 July 1964. The last member to be scrapped was B16/3 No. 61472 on 9 November 1964; none have been preserved. Sub-classes B16/1 Introduced 1920, NER design by Vincent Raven with inside Stephenson valve gear. B16/2 Introduced 1937, LNER rebuilds of B16/1 by Nigel Gresley with Walschaerts valve gear on the outside cylinders and Gresley conjugated valve gear on the inside cylinder. B16/3 Introduced 1944, LNER rebuilds of B16/1 by Edward Thompson with three sets of Walschaerts valve
