The Taff Vale Railway

In 1835, the major industrialists in Merthyr began considering building a railway line from Merthyr to the Bute Docks in Cardiff. To this end, Anthony Hill, owner of the Plymouth Ironworks, contacted Isambard Kingdom Brunel, to estimate the cost of building such a railway – Brunel replied quoting an estimate of £190,649. The industrialists subsequently held a meeting, chaired by Josiah John Guest, at the Castle Inn in Merthyr, to discuss the issue, and decided to request Parliamentary permission to form a company to build the railway. Permission was granted an the company was incorporated the following year.

On 21 June 1836 Royal Assent was given to The Taff Vale Railway Company’s Act, allowing for the creation of the Taff Vale Railway Company. The founding capital of the Company was fixed at £300,000, in £100 share units. The directors were Josiah John Guest, Walter Coffin, Edward Lee, Thomas Guest, Thomas Guppy, Thomas Powell, Christopher James, Thomas Carlisle, Henry Rudhall, William Wait, William Watson, and Peter Maze. Company profits were capped at 7% originally, with a clause allowing for an increase to 9% subject to a reduction in the rates and tolls charged for use of the line.

The Act also capped the speed of the trains on the line to 12 mph (19 km/h), with stiff penalties for any speeding.

Construction of the railway was started in 1836, and the stretch from Cardiff to Navigation House (later named Abercynon) was opened in a formal ceremony on 9 October 1840, with public services starting the next day. The stretch from Abercynon to Merthyr was opened on 12 April 1841. The railway was single-line for its entire length, with passing only possible at or near the stations. It was not until 1857 that it became a double line. Brunel, the chief engineer, had chosen a narrower gauge (4 feet 8.5 inches or 1.435 m) than the 7 foot (2.134 m) gauge he would later choose for his Great Western Railway in order to fit the railway into the narrow space allowed to him by the River Taff valley.

Construction of the main line was relatively straightforward. The line mostly followed the course of the valley, and therefore needed few bridges and no tunnels. Brunel designed an impressive skew stone arch viaduct at Pontypridd, which spanned 110 feet (34 m) over the River Rhondda; the viaduct is still in use today, although it has been supplanted by a second, parallel viaduct. A similar viaduct was built at Quakers Yard.

The TVR’s original station in Merthyr was at Plymouth Street and was opened on 12 April 1841.

This was joined in 1853 by the High Street station of the Vale of Neath Railway. A short joint line (TVR and GWR) was built to connect the TVR line to the new station in 1877. A year later, in August 1878, the Taff Vale transferred all of its passenger services to the High Street station, and used Plymouth Street as a goods depot instead. High Street station thus became the only passenger station in Merthyr, and was used by a total of six separate companies prior to the 1923 grouping. The TVR also opened stations at Merthyr Vale in 1883 and Pentrebach in 1886.

The main line of the TVR was 24 miles (39 km) long. However, no fewer than 23 branch lines took the full length of track to 124 miles and 42 chains (200.40 km). Many of those branch lines were smaller lines taken over by the TVR – in 1841 a branch line was opened in the Rhondda going as far as Dinas, and a second was opened to Llancaiach Colliery. The Rhondda line would subsequently be extended, and by 1856 it had been extended into two lines – one to Maerdy and the other to Treherbert.

The TVR proved its worth immediately. At its peak, two trains a minute passed through the busiest station, Pontypridd. By 1850, the TVR was carrying 600,000 tons (600,000 metric tons) of coal per annum, and was paying a 6% dividend.

The line was conceived as a goods line, carrying iron and coal. However, it also ran passenger services from the beginning. There were two passenger trains each way daily, including Sundays. This was extended to three weekday services in 1844. Single fares from Cardiff to Merthyr were 5 shillings for first class, 4s. for second class, and 3s. for third, and were each reduced by a shilling in 1845.

The Taff Vale Railway continued to operate as a company in its own right until it was incorporated into the Great Western Railway in 1923.

The current railway line between Cardiff and Merthyr now follows the route of the original Taff Vale Railway.
