The plant was developed as a specialist forge. Needing additional supplies of iron, the company, now owned by the Harfords family trust, bought and integrated the
Sirhowy Ironworks and colliery. The company then built four new
cupola furnaces and added steam engine power. later followed by the pioneering
Liverpool & Manchester and the
Stockton & Darlington Railway.
Transport , which was extended to enable limestone to be moved from Cwar y Hendre to the iron and steel works at Ebbw Vale. Timber sleepers and some of the original stone sleepers can still be seen today along this
bridleway The new railway line contracts required additional integration across the production facilities. By the end of the 18th century, both the company and the
Tredegar Iron Company needed to transport raw materials to and products from various ironworks in the upper Ebbw Valley, to
Newport Docks. Developments included: •
Rassa Railroad: tramway built to connect the Sirhowy Ironworks to the
Beaufort Ironworks in Ebbw Vale, and connecting them both to several limestone quarries at Trevil. •
Llanhiledd Tramroad: from Crumlin (low level) north to Ebbw Vale. •
Sirhowy Tramroad: Newport to Crumlin (low level). By 1805, a stretch of tramline had been laid to transport coal and iron ore to Newport Docks, laid jointly by Tredegar Iron Company and the
Monmouthshire Canal Company. Pulled by teams of horses, in 1829 Chief Engineer Thomas Ellis was authorised to purchase a steam locomotive from the Stephenson Company. Built at Tredegar Works, it made its maiden trip on 17 December 1829. On grouping in 1923, all of these railway lines became part of the
Great Western Railway's
Ebbw Vale Line, now operated as a passenger-only service by
Transport for Wales.
New owners and expansion After some commercial failures in the
United States, in 1844 the Hardford's family trust sold the works to partners
Abraham Darby, Henry Dickenson, Joseph Robinson and J Tothill of
Coalbrookdale, with partner Thomas Brown designated managing director. This change started a period of expansion via acquisition, including: • Three blast furnaces of the
Victoria Ironworks from
Lord Llanover, originally built for the Monmouthshire Iron & Coal Company • Abersychan Ironworks, consisting of six blast furnaces • Production facilities in
Pontypool consisting of four furnaces, a forge, tinplate works and coal collieries • Iron ore fields in the
Brendon Hills, Somerset,
Bilbao, Spain and the
Forest of Dean, Gloucestershire In 1850, the company's chemist
George Parry achieved a great economy in blast furnace practice, becoming the first to adopt the cup and cone successfully on blast furnaces. He then conducted experiments in converting iron into
steel, but the company was eventually forced to adopt the patented process of
Henry Bessemer. By 1863, the company was producing 100,000 tons of rail and merchant bars per annum, from 19 blast furnaces, 192 puddling furnaces, and 99 heating furnaces located at Ebbw Vale, Sirhowy, Victoria,
Abersychan, Pontypool and
Abercarn. It also had six wharfs at Newport Docks, the
hematite mine in the Forest of Dean, and
spathic iron ore mines in the Brendon Hills and Spain. ==Ebbw Vale Steel, Iron and Coal Company==
