- Beames 0-8-4T Locomotive Class
- A tank version of the successful class G2 superheated 0-8-0 goods engines, with side tanks, a long bunker and trailing bogie. Intended primarily for the steep gradients in south Wales, where they were used for both passenger and goods trains.
- Beames, H.P.M. (1875 —1948)
- Hewitt Pearson Montague Beames — Apprentice at Crewe under F.W. Webb and became Junior Assistant Works Manager in 1899. After service in the Boer War he became Assistant Outdoor Superintendent at Crewe, dealing with pumping, lifting, dredging and dock machinery. In 1910 he became Personal Assistant to the new CME, C.J. Bowen Cooke. On release from military duties in 1919 he became Deputy CME, and on 1st December 1920 he succeeded Bowen Cooke as CME. Last chief mechanical engineer of the LNWR (1920-1) before its amalgamation with the Lancashire & Yorkshire Railway, he had time to introduce only one new class, an 0-8-4 tank for steep lines in South Wales. With the merger of the LNWR and LYR in 1922, Beames became Divisional Mechanical Engineer, Western Division, under Hughes, and in the following year he was re-designated Mechanical Engineer, Crewe, by the LMS. Beames retired in 1934 at the age of 59.
- Wm. Beardmore & Co.
- The engineering firm of Glasgow, who constructed a number of railway locomotives during and after WW1.
- A device in a machine that allows two parts to rotate or move in contact with each other with reduced friction. The main interest for railway people is the bearing on the axle of a locomotive or carriage.
- Bell Code
- The sequence of bells (block bells) used to communicate between adjacent signal boxes using a standardised code, to offer and accept trains.
- Belpaire Firebox
- The Belpaire firebox was invented by Alfred Jules Belpaire (1820—93) and introduced in 1860. These fireboxes had a bottom narrow enough to fit between the frames of a locomotive. They widened higher up to the width of the barrel, thus providing a larger steam space and greater water surface area in the hottest part of the boiler.
- Benbow Locomotive Class
- In 1903 Alfred the Great class 4-4-0 No.1952 BENBOW was modified to have four independent sets of Joy valve gear in place of two sets. In the original design the outside valves were actuated by rocking levers. The modification was a success and all forty Alfred the Great engines were modified, then being known as the ‘Benbow’ class. The Benbow design was approved by F.W. Webb before his retirement, but implemented by his successor G. Whale.
- BG Van
- A bogie brake van with gangway connections, suitable for use in corridor trains (BR rolling stock code).
- BGZ Van
- A six-wheeled brake van with gangway connections, suitable for use in corridor trains (BR rolling stock code).
