The first Southern Division Locomotive Superintendent was Edward Bury who had been in charge of the London and Birmingham Railway locomotive department at Wolverton since before that railway opened. He resigned in 1847 and later became General Manager of the Great Northern Railway. His successor at Wolverton was James McConnell who had previously worked for the Birmingham and Gloucester Railway at their Bromsgrove works. Among the classes built under his superintendence were the very successful 2-2-2 "Bloomers", developed from a Bury design, and the Wolverton Express Goods 0-6-0 class, built from 1854 to 1863. The Southern Division's trains were longer and heavier, and 0-6-0 locos had been introduced as early as 1845.
