The Rhymney Railway (Rhymney) was virtually a single stretch of main line, some twenty-five miles in length, by which the Rhymney Valley was connected to the docks at Cardiff in the county of Glamorgan, South Wales. Its aim was to gain access to the large iron works and collieries at the extreme north of the Valley. Short extensions, connecting with other railways, gave the Rhymney routes to take its (largely mineral) traffic to the Midlands and the North of England, or opened up connections to collieries and iron works. Some of those routes were worked jointly with other companies.
The original incorporation was in 1854, and the railway was opened in various sections as follows:
Rhymney to Hengoed January 1858
Hengoed - Walnut Tree Junction February 1858
line into Cardiff 1864
Rhymney - Nantybwch, giving access to the London and North Western Railway. This section was worked jointly by the two companies April 1871
Taff - Bargoed giving access to the Dowlais Iron Works. Nine miles in length, with a gradient of 1:40, it had heavy usage. In 1911 the Rhymney conveyed over 300,000 tons of iron and iron ore per annum over this route. Opened January 1 1876
Quaker's Yard - Cyfarthfa authorised 1882
Aber branch 1890
Ystrad Mynach - Cylla Valley 1895
The Rhymney owned 120 locomotives in 1911. By then the total mileage of the Rhymney was over 61 miles; a further 16 miles of 'foreign' track was also worked over. Over two million tons of freight had been carried.

Although the Rhymney was nominally indepedent until absorption in the Great Western Railway at the Grouping of 1923, the same managing director, in 1917, took over control of the line and the Taff Vale Railway and the Cardiff Railway, making them to all and intents and purposes one undertaking.

Notes on the Rhymney (http://www.trackbed.com/companies/r/company_rhy.htm)
The RhymneyRailway (Rhymney) was virtually a single stretch of main line, some fifty miles in length, by which the Rhymney Valley was connected to the docks at Cardiff in the county of Glamorgan, South Wales.
The first workshops for the railway were in Cardiff, opening in 1857 but, as their work increased, there was insufficient room for expansion, and Caerphilly railway works was opened in 1899.
Although the Rhymney was nominally independent until absorption in the Great Western Railway at the Grouping of 1923, the same managing director, in 1917, took over control of the line and the Taff Vale Railway and the Cardiff Railway, making them to all and intents and purposes one undertaking.
Cardiff is also the terminus of both the Taff Vale and the Rhymneyrailways, the latter affording the London and North-Western railway access to the town.
The opening of the Taff Vale railway in 1840 and of the South Wales railway to Cardiff in 1850 necessitated further accommodation, and the trustees of the marquess (who died in 1848) began in 1851 and opened in 1855 the East Bute dock and basin measuring 464 acres.
The Rhymneyrailway to Cardiff was completed in 1858 and the trade of the port so vastly increased that the shipment of coal and coke went up from 4562 tons in 1839 to 1,796,000 tons in 1860.
