Richard Trevithick was a British inventor and mining engineer. The son of a mining captain, and born in the mining heartland of Cornwall, Trevithick was immersed in mining and engineering from an early age. He was an early pioneer of steam-powered road and rail transport, and his most significant contributions were the development of the first high-pressure steam engine and the first working railway steam locomotive. The world's first locomotive-hauled railway journey took place on 21 February 1804, when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales.
The Taff Vale Railway (TVR) was a standard gauge railway in South Wales, built by the Taff Vale Railway Company to serve the iron and coal industries around Merthyr Tydfil and to connect them with docks in Cardiff. It was opened in stages in 1840 and 1841.
Merthyr Tydfil is the main town in Merthyr Tydfil County Borough, Wales, administered by Merthyr Tydfil County Borough Council. It is about 23 miles (37 km) north of Cardiff. Often called just Merthyr, it is said to be named after Tydfil, daughter of King Brychan of Brycheiniog, who according to legend was slain at Merthyr by pagans about 480 CE. Merthyr generally means "martyr" in modern Welsh, but here closer to the Latin martyrium: a place of worship built over a martyr's relics. Similar place names in south Wales are Merthyr Cynog, Merthyr Dyfan and Merthyr Mawr.

The Clydach Gorge is a steep-sided valley in south-east Wales down which the River Clydach flows to the River Usk. It runs for 5.6 kilometres (3.5 mi) from the vicinity of Brynmawr in Blaenau Gwent eastwards and northeastwards to Gilwern in Monmouthshire. The Gorge was one of the first locations in the region to be industrialised though it still retains its natural environment. It has long been an important transport corridor between Abergavenny and the lowlands of Monmouthshire and the northeastern quarter of the South Wales Coalfield. It is now exploited by the A465 Heads of the Valleys trunk road which runs between Abergavenny and Swansea and which serves the Heads of the Valleys sub-region.

The Sirhowy Tramroad was a plateway built to convey the products of ironworks at Tredegar to Newport, South Wales. It opened in 1805 between Tredegar and Nine Mile Point, a location west of Risca, from where the Monmouthshire Canal Company operated a tramroad to Newport. The Sirhowy Tramroad was operated at first by horse traction, but early locomotives were used, and a passenger service was operated.
The Merthyr Tramroad was a 9.75 miles (15.69 km) long line that opened in 1802, connecting the private lines belonging to the Dowlais and Penydarren Ironworks with the Glamorganshire Canal at Abercynon, also serving the Plymouth Ironworks along the way. Famous as the line on which Richard Trevithick's experimental locomotive hauled the first train to carry a load. It was largely superseded when the Taff Vale Railway opened in 1841 and sections gradually went out of use over the two decades from about 1851.
