as the manager of the locomotive department on a salary, with a profits bonus. Locomotive Works At first the Works was used for the maintenance and repair of locomotives purchased from outside firms. Two locomotives were built there in 1845/6, and another in 1848, but following enlargement of the buildings and increased facilities, they were turned out in quantity. In total, 166 locomotives were built at Wolverton. These included three varieties of the 2-2-2 LNWR Bloomer Class, 86 of the Wolverton Express Goods 0-6-0 and four varieties of 0-4-2. In 1846 the London & Birmingham became part of the London and North Western Railway (LNWR); Bury resigned in 1847 and was succeeded by James E. McConnell as locomotive superintendent of the LNWR Southern Division. An innovative engineer who during his tenure experimented with hollow axles, rubber springs, brakes working on the rails, and elaborate boilers and fireboxes, but perhaps his greatest claim to fame is the 2-2-2 Bloomer type of 1851, which was closely based on a Bury design. A total of seventy-four were built in three classes between 1851 and 1862, similar in design and layout but different in dimensions. In 1861 the cost-conscious Richard Moon was appointed Chairman of the LNWR, and became very critical of McConnell; after the Board passed a motion of censure on him, McConnell was obliged to resign in March 1862. In 1862, Moon drove through a policy that Crewe would become the sole locomotive manufacturing centre for the LNWR, and so the last of the 166 Wolverton-built locomotives left the works in September 1863. Carriage works Having retained its maintenance role, in 1865 Wolverton was designated as the LNWR Carriage Works, eventually becoming the largest carriage works in the UK. Initially Wolverton produced numbers of six-wheel carriages on a rigid wheelbase. In 1873 a sleeper service was introduced to Glasgow, and in 1875 to Liverpool and Holyhead. The carriages for these were again three-axle, limited it is said, to by the traverser in the Euston carriage sheds. This remained the pattern for many years, though some used Webb's patent "radial truck". The 1880s saw the introduction of first-class twin-car sets with an interconnecting gangway. The 1881 sleeping cars for the Irish Mail were of this form, and in 1889 some of the first-class twins were adapted to become the LNWR's first dining cars. In 1883, sleeping cars were introduced on the Glasgow service
