The Barry Railway Company was a railway and docks company in South Wales, first incorporated as the Barry Dock and Railway Company in 1884.

In addition, the Taff Vale did not have the required capacity for the mineral traffic using the route, leading to lengthy delays in getting to Cardiff.

The Llancaiach Branch railway line was a mineral branch line in Glamorganshire, South Wales. It was authorised in 1836 as part of the Taff Vale Railway, and its purpose was to connect collieries at Llancaiach and bring their output to Cardiff for onward shipment. It was designed by Isambard Kingdom Brunel and built on the standard gauge. It opened in 1841 from a junction with the Merthyr line immediately south of Abercynon. It was intended to be horse worked, and included a self-acting rope-worked inclined plane near the junction. The collieries were slow to use the line, preferring their customary use of a tramroad and the Glamorganshire Canal, and the value of the line was diminished when the Taff Vale Extension line, an east-west connecting line belonging to the Newport, Abergavenny and Hereford Railway, intersected it and cut off the colliery connections, and the line became dormant.
