The Padarn Railway was a narrow gauge railway line in North Wales, built to the unusual gauge of 4 ft. Its purpose was to carry slate the seven miles (11 km) from Dinorwic Quarry (53.1213°N 4.1152°W) to Port Dinorwic (53.1859°N 4.2090°W). The line replaced the previous Dinorwic Railway from 3 March 1843, initially using horses, converting to steam haulage on 23 November 1848. The railway was formally titled the Dinorwic Quarries Railway or Dinorwic Quarry Railway, but the informal "Padarn Railway" stuck and was widely used.

Dinas is a station on the narrow gauge Welsh Highland Railway, which was built in 1877 as the North Wales Narrow Gauge Railways Moel Tryfan Undertaking to carry dressed slate for trans-shipment to the LNWR.

In 1951, British Railways closed their part of the station but the line through the station remained open until the line from Caernarvon to Afon Wen was closed in 1964.

Gilfach Ddu are a series of well preserved Grade I listed industrial buildings built to serve the Dinorwic slate quarry near the Llanberis in Caernarfonshire, North Wales. The workshops are a complex of repair and maintenance buildings, that were built in 1870 to build and maintain the machinery used in the quarry. The complex includes saw sheds, patternmaking shops, a foundry with copula, blacksmiths shops, fitting shops, stores, engine sheds, a canteen, the chief engineers house, a hand operated crane and two waterwheels which provided the site with its power. Since 1972 the buildings have housed the National Slate Museum.
