The Global Centre of Rail Excellence (GCRE) is a proposed train, railway infrastructure and technology testing facility, located in Onllwyn, Wales, where the site sits on the border between Neath Port Talbot and Powys. The centre is located on a site previously used for coal mining and a coal washery, with some 550 acres (220 ha) given over to the new testing centre, which will be unique in Europe due to having a track for testing rail vehicles at high speed, and another test track dedicated to railway infrastructure. Ownership of the site was transferred to the Welsh government in October 2022. Construction will take place in three phases, initial works focus on sidings, then the two electrified test tracks; more comprehensive facilities, including maintenance and research buildings, a business park, and hotel, are to be built in the third phase. The GCRE is expected to open sometime in 2024. In the long term, it is intended for the GCRE to be operated as a commercial entity and majority owned by the private sector; a competitive bidding process for investors to purchase a majority stake in the company has been launched with the aim of achieving this model. Partnerships and other agreements have been struck by the GCRE with various other organisations, including Talgo, Hitachi, and Thales’ Ground Transportation Systems, to make use of the site's facilities; a membership model has been envisioned by the GCRE's management. While considerable attention has been paid to garnering business domestically, the company also offers its services to international railway companies, particularly those on the European continent.

Rheola House is a Grade II* listed country house between Glynneath and Resolven, in the Neath valley, South Wales. Designed by John Nash, it was built between 1812 and 1814 for Nash's cousin, John Edwards. It passed through inheritance to members of the Edwards, Vaughan, and Lee families, until in 1939, with the house becoming run down, it was bought by an aluminium company for use as offices, and part of the land was put to industrial uses. In 2012 an application was made for housing on the industrialised area, to enable restoration of the house and a leisure complex to sustain the estate. The application was granted in 2014. The gardens and park around the house are designated Grade II on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales.

Seven Sisters was an electoral ward of the Welsh principal area of Neath Port Talbot county borough. The ward, which included, as well as Seven Sisters proper, the lesser settlements of Bryndulais and Nant-y-cafn, was coterminous with the area served by the Seven Sisters Community Council. Lying in the upper Dulais Valley – in which coalmine workings are still very evident (the village is named after Seven Sisters Colliery which closed in the early 1960s) – the area is characterized by extensive forestry to the north, east and south, and open moorland in the northwest and central areas. Following a 2020 boundary review by the Local Democracy and Boundary Commission for Wales, Seven Sisters was joined by the neighbouring communities of Crynant and Onllwyn to become 'Crynant, Onllwyn and Seven Sisters', effective from the 2022 local elections.
