The [[North Eastern Railway (UK)|North Eastern Railway]] '''Class S3''', classified '''B16''' by the [[London and North Eastern Railway|LNER]], was a class of [[4-6-0]] [[steam locomotive]] designed for mixed traffic work. It was designed by [[Vincent Raven]] and introduced in 1920. The earlier members of this class were fitted with Westinghouse Brakes - all of this equipment was removed during the 1930s.

==History==
In 1915, the British Government took control of the country's railways. This paused the development of new locomotives, rolling stock, and infrastructure. One such railway, the North Eastern Railway, was planning to electrify its portion of the [[East Coast Main Line]] between York and Newcastle.

In the same year, Chief Mechanical Engineer, Vincent Raven, was appointed as the Superintendent of the Royal Arsenal in Woolwich and would not return to Darlington until 1919. Standing in for Raven was his assistant, Arthur Cowie Stamer.

Meanwhile, plans were made to nationalise the railways. However, doing so would require standardized locomotives and rolling stock under the Association of Railway and Locomotive Engineers (ARLE). While the ARLE would agree on a mixed-traffic [[2-6-0]] with 5-foot 8-inch driving wheels, the North Eastern Railway and the London & North Western Railway opted out of the design process. Instead, Stamer instructed Chief Draughtsman George Heppell to produce drawings for three locomotive assignments: express passenger, express freight, and mineral traffic. These were to be built with ARLE specifications and contemporary Darlington practices. Notably, the locomotive had to share valve gear, cylinders, and boilers with at least one other class, which was common for railways in the UK at the time. Each locomotive also had to weigh at least 75 tons without a tender, with an axle loading no greater than 20 tons. Two of these drawings were approved: a [[4-6-0]] for express freight traffic and an [[0-8-0]] for mineral traffic. Both had three cylinders with Stephenson link motion. These had an 18.5-inch bore by a 26-inch stroke. The boilers were based on the [[NER Class Z|Z Class]] [[4-4-2]] and were pressed at 180 psi. To provide a good balance between speed and adhesion, 5-foot 8-inch driving wheels were chosen.{{sfn|Swinger|2002|page=54}} This fell in line with the Mogul drawn up by the ARLE, with both the Great Northern Railway and Great Western Railway using driving wheels of the same diameter for express freight traffic and suburban passenger trains.

As previously stated, the boiler would also be interchangeable with the [[NER Class T3|T3 Class]] (LNER Q7) [[0-8-0]]s,{{sfn|Nock|1954|page=180}} much like the S2s, which had interchangeable wheels and cylinders with the S Class and interchangeable cylinders and boilers with the [[NER Class T2|T2 Class]] (LNER Q6) 0-8-0s. {{Relevance inline|date=June 2025}} The result was the S3 Class (LNER B16). After approval, Stamer placed an order for 10 locomotives of the S3 Class in November 1918, with the first five members, Nos. 840-844 appearing in December 1919 from [[Darlington Works]].

==Post-NER==
Seventy S3/B16 locomotives were built between 1919 and 1924. The NER began numbering this class 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, 38 locomotives passed to the [[London and North Eastern Railway]] (LNER), which built thirty-two more{{sfn|Swinger|2002|page=54}} starting with No. 2366 on 4 January 1923 and ending with Nos. 1384 and 1385 on 1 January 1924.{{Citation needed|date=June 2025}} 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.{{sfn|Bradley|1988|page=85}}{{sfn|Bradley|1988|page=27}}

Under the LNER, the B16s hardly ever left the North East. Their duties included fast freights, express passenger trains, excursions to [[Scarborough railway station|Scarborough]], and even [[football specials]]. During World War II, some of the B16s moved to the [[Great Central Main Line]], working around [[Banbury railway station|Banbury]] and [[Woodford Halse railway station|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 [[LNER Class V2|V2]] [[2-6-2]] or a [[LNER Thompson Class B1|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).{{sfn|Swinger|2002|page=55}}

==Withdrawals==
One locomotive, No. 925, was badly damaged (along with [[LNER Class A4 4469 Sir Ralph Wedgwood|A4 4469 ''Sir Ralph Wedgwood'']]) during a German air-raid on York on 29 April 1942, and was subsequently scrapped.{{sfn|Bradley|1988|page=28}} The first withdrawal under British Railways 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. Due to the complicated maintenance and proneness to leaking piston valves, the B16/1s were all retired first. 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.

*On 27 June 1928, locomotive No. 2369 was [[Darlington rail crash|involved in a head-on collision]] with an excursion train at {{rws|Darlington}}, [[County Durham]] whilst it was shunting a parcels train. Twenty-five people were killed and 45 were injured.<ref name=Hoole3>{{cite book |last=Hoole |first=Ken |author-link=Ken Hoole |title=Trains in Trouble: Vol. 3 |year=1982 |publisher=Atlantic Books |location=Redruth |isbn=0-906899-05-2 |pages=27, 35 }}</ref>
*On 5 January 1946, locomotive No. 842 was [[Browney rail crash|hauling a freight train which became divided]] on the [[East Coast Main Line]] in [[County Durham]]. The train was brought to a halt at Browney Signalbox, but the rear portion crashed into it. The wreckage fouled signal cables, giving a false clear to a passenger train coming in the opposite direction. This train then collided with the wreckage. Ten people were killed and eight were severely injured.<ref>{{cite book |last1=Hoole |first1=K. |title=The East Coast main line since 1925 |date=1977 |publisher=I.
