The Heart of Wales Line

The Heart of Wales line is also known as Central Wales line (Welsh: Rheilffordd Canol Cymru) and also included routes through Gowerton, where the railway crossed the West Wales lines and ran through Dunvant and Killay then down through the Clyne Valley to Blackpill, and then along the sea wall to Swansea Bay station, (near the former slip bridge) before finally reaching Swansea Victoria railway station.
This section, originally built by the Llanelly Railway and Dock Company to compete with the Great Western Railway and break the monopoly they held on Swansea Dock, closed in 1964.

Nationalisation of the railways had removed the need for competing routes, and the running down and closure of Swansea North Dock ended the need for freight services on this section. Trains now use the original LR main line to reach the West Wales lines at Llandeilo Junction and thence Llanelli and (after a reversal) Swansea.

North of Llandovery, the route was opened in stages between 1861 and 1868 by a number of different companies (all backed by the LNWR) – the Knighton Railway, the Central Wales Railway and Central Wales Extension Railway.

The 1963 Beeching Report proposed the entire Central Wales line be closed but this was refused by the Ministry of Transport for the Pontardulais to Swansea Victoria section. As a rural branch line, it survived the Beeching Axe since it carried freight traffic, serving the steelworks at Bynea and industrial areas such as Ammanford and Pontarddulais, linking them with the docks at Llanelli. The line also passed through six marginal constituencies.

During engineering work, the line is still occasionally used as a diversionary freight route. The basic service over the line since the seventies has remained more or less constant, with four or five trains per day in each direction on weekdays and two or three on Sundays.

The line is single track throughout (except for a few miles at the southern end shared with the Swansea District line) and has been operated under a Light Railway Order since 1972. There are five passing loops, at Llandeilo, Llandovery, Llanwrtyd, Llandrindod and Knighton. Unless "Out of Course" working occurs the Llanwrtyd passing loop is used on two of the Monday – Saturday services and the Llandrindod passing loop is in use on the other two and also on the Sunday services.
The signalling was modernised in 1986, when a system known as No Signalman Token Remote working was introduced.

This is overseen by the signaller at Pantyffynnon, with the token instruments at the aforementioned five passing loops being operated by the train crew (the surviving signal boxes at each station having been closed as part of the modernisation scheme and the points converted to automatic operation by British Rail).

Knighton railway station serves the market town of Knighton in Powys, Wales, although the station itself is located in Shropshire, England (the border is immediately adjacent to the south side of the station and runs through the car park). It lies 321⁄2 miles (52.3 km) south west of Shrewsbury (by railway line) on the Heart of Wales Line. The railway station is located below street level at Station Road beside the River Teme and about 1⁄2 mile (0.8 km) from the centre of the town.

    Sugar Loaf Halt Sugar Loaf halt is a railway station in Powys, Wales, and is the most geographically remote station on the Heart of Wales Line. It is located one mile (1.5 kilometres) northeast of a small but prominent knoll known as Sugar Loaf, around which the A483 road loops. The line through here was opened by the Central Wales Extension Railway in 1868. The passing loop was removed when station was closed to passengers in 1965 but the station subsequently reopened to traffic in 1984. The station's name in Welsh is Dinas y Bwlch, however, in Welsh station announcements, the station is referred to as Pen-y-fâl, the name given to the mountain of the same name in Monmouthshire. The station sees very few passengers; in 2010/2011 an estimated 84 passengers used the station and in 2014 it was reported that the station was averaging five passengers per month. In 2017/2018 it increased its passenger usage by nearly 710% from the previous year, taking it to as many visitors in the year as the previous 17 years combined when it was announced that it was Wales’ least used station. Between July 6, 2020 and August 21, 2021, trains did not call at the station due to the short platform and the inability to maintain social distancing between passengers and the guard when opening the train door during the Covid pandemic. This station is a request stop used mainly by trekkers and cyclists, since it is the nearest stop to the Sugar Loaf vantage point, although it was originally built to serve a number of cottages occupied by railway workers. The children of the workers travelled by train to school in Llanwrtyd Wells. South of the station the line reaches the summit at 820 feet (250 m) above sea level and then passes beneath the hills via the 1,001-yard (915 m) Sugar Loaf tunnel, which is approached by gradients as steep as 1 in 60. It then descends steadily for the next 8+1⁄2 miles (13.7 km) down to Llandovery. The climb up to the summit here was a challenging one for train crews in steam days (especially northbound) and the use of banking locomotives was commonplace.

    Llandovery Station viewed from the train. Llandovery railway station serves the market town of Llandovery, Carmarthenshire, Wales. The station is on the Heart of Wales Line 42 miles (68 km) north east of Swansea and is located at Tywi Avenue. The station was opened by the independent Vale of Towy Railway company in 1858 as the terminus of a branch from Llandeilo, although the VoTR was soon leased by the Llanelly Railway (which had built the route northwards from Llanelli in stages between 1833 and 1852.) The Llanelly company in turn soon became part of the GWR. The LNWR's Central Wales Extension Railway arrived from the north a decade later to complete the through route between Craven Arms and Swansea, with the LNWR and GWR taking joint control of the Llandovery to Llandeilo section. The station sits at the bottom of an 8+1⁄2 miles (13.7 km) descent from the line's southern summit at Sugar Loaf tunnel and until August 1964, a locomotive shed was in operation here to house the engines used for assisting northbound trains (the ruling gradient on this section being 1 in 60). There is a passing loop and level crossing (of the A40 road) at the station, but the signal box that formerly operated them was closed in 1986. The token instruments for the single line and crossing barriers are both operated by the train crew under the supervision of the signaller at Pantyffynnon. Refurbished station buildings were opened by Prince Charles in June 2011, some 19 years after they were closed. The station is unstaffed and has no ticket machine, so all tickets need to be purchased prior to travel or on board the train. There are shelters, CIS screens and customer help points on each platform, whilst a local volunteer group runs a cafe and gallery in the main station building. Step-free access is provided to both platforms
