which was intended to promote the development of the valley's coal reserves. In February 1807, approval was given to carry passengers along the line, when one of the original proprietors, Benjamin French, offered to pay the company the sum of twenty pounds in lieu of tolls for the right to do so for twelve months from the following quarter day, 25 March 1807. This is usually cited as the date when the first regular service carrying passengers between Swansea and Oystermouth began, thus giving the railway the claim of being the first passenger railway in the world. Passenger services operated from The Mount, the world's first recorded railway station. The venture was evidently a success because the following year French joined with two others in offering the increased sum of twenty five pounds to continue the arrangement for a further year, but the construction of a turnpike road parallel to the railway in the mid-1820s robbed it of much of its traffic and the passenger service (by that time in the hands of one Simon Llewelyn) ceased in 1826 or 1827, ironically just as events elsewhere in the United Kingdom (particularly in the north east of England) were paving the way for the development of railways as a truly national and international transport system for both goods and passengers. In its early days the line operated in the same manner as the contemporary canals and turnpike roads. Tolls and charges were laid down in the enabling Act of Parliament and any trader could use the line on provision of a suitable waggon and after paying the appropriate toll to the owning Company. The railway was laid in the form of a plateway, with the rails being approximately apart. After cessation of the passenger service the line became derelict and the original company of proprietors virtually moribund. The Clyne valley branch was relaid in 1841/2 and extended for a further mile (as a private line) to the Rhydydefaid colliery where George Byng Morris, the son of one of the original proprietors, had started to exploit the coal and iron reserves of the valley. From about 1855, George Byng Morris took the line in hand, relaid it with edge rails (i.e. as a conventional railway) to the standard gauge of and reintroduced a horse-drawn passenger service between Swansea and a terminus at The Dunns in Oystermouth.
