- Ahrons, Ernest Leopold (1866—1926)
- Author of ‘The British Steam Railway Locomotive 1825–1925’ (Locomotive Publishing Company 1927). A standard work on the subject, for long regarded as a classic. His earlier writings were under the pen name ‘Meteor’.
- Allan, Alexander (1812—1878)
- Works Manager at Crewe Works 1843–53, under Francis Trevithick.
- Baker, William (1817—1878)
- In 1852 was appointed by the LNWR as engineer of the Southern Division to succeed R.B. Dockray. On the death of Robert Stephenson in 1859 Baker was appointed chief engineer of the LNWR.
- Barlow, William Henry (1812—1902)
- Chief Civil Engineer for the Midland Railway between 1844 and 1858. His works included the MR line from St. Pancras, London to Bedford including St. Pancras Station itself.
- Baxter, Bertram (?—1966)
- ‘British Locomotive Catalogue 1825-1923’ Compiled by Bertram Baxter, edited by David Baxter. (Moorland Publishing Company 1979). Vol.1 is the index, Vol.2a and Vol.2b list every locomotive ever built by or for the LNWR and its constituent companies.
- 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.
- Bowen Cooke, Charles J (1859—1920)
- Chief Mechanical Engineer of the LNWR, Bowen Cooke introduced superheating to that railway with conspicuous success, taking great care to get things right. His comparative trials between non-superheated and superheated units were more meticulous than most. His George the Fifth 4-4-0, often considered the best passenger locomotive the LNWR ever had, was a superheated version of the existing Precursor type, while his Prince of Wales 4-6-0 was a similar updating of the existing Experiment. His major new design was the Claughton class, a handsome four-cylinder 4-6-0 that never quite lived up to its promise, probably because of poor air access to the fire and inefficient draughting in the smokebox. He was in office from 1908 to 1920.
- Bury, Edward (1794—1858)
- In 1836 Edward Bury contracted to work the London & Birmingham Railway’s trains, but this contract system — by which he was to be paid on a mileage basis, per passenger and per ton — was never implemented and from 1839 he was employed as Manager of the L&BR Locomotive Department. On the formation of the LNWR he became Locomotive Superintendent of that company’s Southern Division, but resigned with effect from March 1847.
Later Bury became General Manager and Locomotive Engineer of the Great Northern Railway. He also advised on the building of three railway works, Swindon, Wolverton and Doncaster.
- Caprotti, Arturo (1881—1938)
- Italian locomotive engineer and designer of the ‘poppet’ type valve gear, claimed to improve engine efficiency. However, the design was hard to maintain, and was bettered by long-travel piston valves.
- Churchward, George Jackson (1857—1933)
- Churchward worked for the GWR, but Stanier took Churchward’s ideas to the LMS, and applied them in a virtually undiluted form.
- Crampton, Thomas Russell (1816—1888)
- Civil and locomotive engineer working in Britain for the GWR (early 1840s) with Gooch, and later the LNWR. His design trait was a large, single driving wheel behind the firebox, allowing for a low-slung boiler. After the LNWR, his designs were bought by French, German and Belgian Railways.
- Edmondson, Thomas (1792—1851)
- After an early life as journey-man cabinet maker, in 1836 he obtained employment as a clerk on the Newcastle & Carlisle Railway. In 1837 he invented a machine for printing railway tickets on cards 2¼in x 1 3/16in, and a press for stamping dates on the tickets. The NCR showed no interest in his inventions, so he successfully applied to the Manchester & Leeds Railway. His system was soon adopted for use throughout the country and elsewhere in the world. Edmondson patented his inventions and charged railways 10s a mile per year for their use. He was always generous with the proceeds. His system avoided the time-consuming labour of writing out individual tickets for passengers.
