Some other notable structures were added when smaller companies were amalgamated into the GWR. These include the South Devon Railway sea wall, the Cornwall Railway's Royal Albert Bridge, and Barmouth Bridge on the Cambrian Railways. In the early years the GWR was managed by two committees, one in Bristol and one in London. They soon combined as a single board of directors which met in offices at Paddington. The Board was led by a chairman and supported by a Secretary and other "officers". The first Locomotive Superintendent was Daniel Gooch, although from 1915 the title was changed to Chief Mechanical Engineer. The first Goods Manager was appointed in 1850 and from 1857 this position was filled by James Grierson until 1863 when he became the first general manager. In 1864 the post of Superintendent of the Line was created to oversee the running of the trains. Early trains offered passengers a choice of first- or second-class carriages. In 1840 this choice was extended: passengers could be conveyed by the slow goods trains in what became third-class. The 1844 Railway Regulation Act made it a legal requirement that the GWR, along with all other British railways, had to serve each station with trains which included third-class accommodation at a fare of not more than one penny per mile and a speed of at least . By 1882, third-class carriages were attached to all trains except for the fastest expresses. Another parliamentary order meant that trains began to include smoking carriages from 1868. Special "excursion" cheap-day tickets were first issued in May 1849 and season tickets in 1851. Until 1869 most revenue came from second-class passengers but the volume of third-class passengers grew to the extent that second-class facilities were withdrawn in 1912. The Cheap Trains Act 1883 resulted in the provision of workmen's trains at special low fares at certain times of the day. The principal express services were often given nicknames by railwaymen but these names later appeared officially in timetables, on headboards carried on the locomotive, and on roofboards above the windows of the carriages. For instance, the late-morning "Flying Dutchman" express between London and Exeter was named after the winning horse of the Derby and St Ledger races in 1849. Although withdrawn at the end of 1867, the name was revived in 1869 – following a request from the Bristol and Exeter Railway – and the train ran through to Plymouth. An afternoon express was instigated on the same route in June 1879 and became known as "The Zulu".
