The London and North Eastern Railway (LNER) Thompson Class B2 was a class of 4-6-0 steam locomotive. It was introduced in 1945 as a two-cylinder rebuild (with diagram 100A boiler) of the three-cylinder LNER Class B17. Ten were rebuilt from Class B17 but no more were rebuilt because of the success of the LNER Thompson Class B1.

Numbering

The LNER renumbered its locomotive stock during the period that these locomotives were being rebuilt, so some were renumbered at the time that they were rebuilt, some before rebuilding, and some after rebuilding. The renumbering plan for class B2 was the same as for class B17: in each case the first two digits were altered from 28 to 16. Thus 2803 became 1603 at rebuilding in October 1946; 2807 had already become 1607 (December 1946) prior to rebuilding in May 1947; and 2814 (rebuilt November 1946) became 1614 in December 1946. [1] Between 1948 and 1950, British Railways increased these numbers by 60000; no. 61644 was so renumbered at the time of its rebuilding in March 1949. [2]

Names

The rebuilt locomotives kept their names:

Renaming

Two of the locomotives were renamed. No. 1671 was the official Royal engine and for this purpose it was renamed Royal Sovereign in April 1946.

The second renaming occurred after the withdrawal of 61671 in September 1958: in October, the name Royal Sovereign was transferred to no. 61632, which then became the official Royal engine. [3] All members of the class were scrapped.

Operation

Two B2s were kept at Cambridge for hauling the Royal Train in East Anglia, [4] [5] predominantly to and from Wolferton which was the nearest to Sandringham House, these being renamed Royal Sovereign and 61617 Ford Castle as the reserve. There were three sets of drivers and firemen allocated specifically to work the "Royal" engines and they did not work unless operated by one of these teams. [6] It was Ford Castle which was one of the locomotives used to haul the funeral train of King George VI on 11 February 1952, hauling the train from Wolferton as far as King's Lynn from where 70000 Britannia took over for the rest of the journey to King's Cross. [7]

Other than the two locomotives allocated to Cambridge, the remaining locomotives were mainly allocated to Colchester and were predominantly used on services between Liverpool Street and Clacton. [4] Many publications list "B17/B2" together and consider the types interchangeable which may lead to the type being overlooked; a list of locomotives allocated to Colchester in 1951 and labelled as "B2/B17" shows eight B2s and no B17s. [8]

Due to the size of the turntables on the Great Eastern section, locomotives were sometimes used with tenders that were shorter than those originally designed. At least one B2 was recorded as being paired with a tender of NER origin rather than the longer B17 tender. [9]

The last B2 was withdrawn in 1959. [10]

<span class="mw-page-title-main">NER Class X</span>

The NER Class X was a class of 4-8-0T tank locomotive designed by Wilson Worsdell for the North Eastern Railway. They were intended for use as powerful shunting engines to arrange and move coal wagons for loading into ships. In total 15 were built, 10 by the NER between 1909 and 1910, and a further five in 1925 by the London and North Eastern Railway (LNER). They had three cylinders with divided drive: the inside cylinder driving the leading axle, the outside cylinders driving the centre.

<span class="mw-page-title-main">British Rail Class EF1</span>

The Class EF1 was a class of electrically powered locomotives built by the North Eastern Railway from 1914. They were built to haul coal trains from the mines at Shildon to the docks at Middlesbrough. In common with other LNER electric locomotives, no classification was given to these locomotives until 4 October 1945, when nos. 3-12 were all classified EB1 although only no. 11 was actually modified for banking. It was expected that all the locomotives would be similarly modified, but this did not happen, and the remaining locos were classified as EF1.

<span class="mw-page-title-main">NER Class S</span>

The North Eastern Railway Class S was a 4-6-0 type of steam locomotive designed for express passenger workings. The first example was built in 1899. They were very similar to the NER Class S1, except for the smaller wheels of the former.
