James E. McConnell

James Edward McConnell (1815–1883) was a British locomotive engineer who served as Locomotive Superintendent of the London and North Western Railway's Southern Division at Wolverton Works from 1847 to 1862, developing a distinctive engineering approach that differed markedly from the contemporary practice of Francis Trevithick at Crewe and creating the celebrated 'Bloomer' single-driver express locomotives that became the most recognisable LNWR express engines of the 1850s.

Born in 1815 — probably in Scotland or Ireland, sources differ — McConnell was apprenticed at Forrest of Glasgow and subsequently gained experience on several early British railways before becoming Locomotive Superintendent of the Birmingham and Gloucester Railway, a Midland Railway predecessor. He was appointed to the LNWR's Southern Division at Wolverton in 1847, inheriting a locomotive fleet associated with Edward Bury's distinctive D-framed design philosophy.

McConnell's most celebrated designs were the 'Bloomer' 2-2-2 single-driver express engines of 1851 and their 2-2-2 successors — large, powerful singles with outside frames and, unusually for British practice, outside cylinders, that were distinguished by their bright crimson lake livery and their absence of the coupling rods that gave contemporary coupled engines their familiar profile. The Bloomers' nickname came from Amelia Bloomer's reformed dress controversy of the same period, the exposed wheels of the outside-cylinder singles being thought analogous to the visible legs of Bloomer's reformed costume. They worked the LNWR's Birmingham and Euston expresses with distinction throughout the 1850s.

McConnell resigned in 1862 when the LNWR's Board consolidated all locomotive matters under Ramsbottom at Crewe, eliminating the Southern Division's engineering independence. He went into private engineering practice and died at Stourbridge on 11 June 1883.
