Cwm-y-Glo railway station

Cwm-y-glo is a small village in Wales, 4+1⁄2 miles (7 km) east of Caernarfon, between Llanberis and Llanrug. It is in the Arfon Parliamentary constituency, the community of Llanrug, and the Gwynedd Council electoral ward. Cwm-y-glo ward includes Ceunant and Pont-rug and has a population of around 1,000.The focus of the village is on the original roadway, now bypassed by the A4086 road, which follows the approximate line of the former railway. To the east of the village lies the flood plain of Afon Rhythallt (an extension of the Afon Seiont) and consequently some houses on the eastern side of the old road (which lie below the level of the main road) suffer flooding. The village is mainly residential, but has a number of shops and small businesses. Menter Fachwen is a local charity offering work to adults with disabilities. The community is policed from Llanberis and has a dedicated Community Beat Manager.

The village is policed from Llanberis and has a dedicated Community Beat Manager.

Penllyn (LLR) railway station is the northern terminus of the Llanberis Lake Railway (LLR), located near Llanberis, Gwynedd, Wales. The station has no platforms and passengers are not allowed to board or alight. Most of the LLR was laid around 1970 on part of the trackbed of the closed and lifted Padarn Railway. The line opened between Gilfach Ddu (LLR) and Cei Llydan on 28 May 1971, being extended northwards to Penllyn in 1972, changing Cei Llydan from a terminus to a through station. For thirty years Gilfach Ddu (LLR) was the new line's southern terminus, situated a short distance south of the site of the Padarn Railway's former workmen's station, also named Gilfach Ddu. In 2003 a wholly new extension was opened south westwards, with Llanberis (LLR) station as the line's new southern terminus. With this extension Gilfach Ddu (LLR) changed from a terminus to a through station. Penllyn (LLR) is situated a short distance south of the site of the former Padarn Railway Pen-y-Llyn workmen's station. The line and station primarily serve tourists and railway enthusiasts.

The Padarn Railway was a narrow gauge railway in North Wales, built to the unusual gauge of 4 ft (1,219 mm). It carried slate seven miles (11 km) from Dinorwic Quarry to Port Dinorwic. The line opened on 3 March 1843, replacing the Dinorwic Railway. It initially used horses, but was converted to steam haulage on 23 November 1848. The railway was formally titled the Dinorwic Quarries Railway or Dinorwic Quarry Railway, but informally "Padarn Railway" was widely used. The railway officially closed on 3 November 1961. The locomotive Dinorwic performed the last practical services by hauling the track-lifting trains.

The River Rhythallt (Welsh: Afon Rhythallt) is a river in Gwynedd, North Wales whose source is Llyn Padarn. It flows in a northwesterly direction past the village of Brynrefail, Gwynedd and changes its name to Afon Seiont downstream of Pont Rhythallt in Llanrug. The Afon Seiont eventually reaches the sea at Caernarfon. The river has a broad flood plain which occasionally threatens homes in the village of Cwm-y-glo.

Penisa'r-waun is a small village which is located 4 miles to the east of Caernarfon and a mile to the northeast of Llanrug on the A4547 in Gwynedd, north-west Wales.

The Glynrhonwy quarries (also known as the Glyn-Rhonwy quarries) were two adjacent quarries in the Glynrhonwy area, north-west of Llanberis, in Carnarvonshire (now Gwynedd), Wales. They were: Upper Glynrhonwy quarry, known locally as "Glyn Ganol" or "Middle Glyn", which operated from 1861 to 1930, and Lower Glynrhonwy quarry, known locally as "Captain Taylor's Quarry", which operated from the early 1700s to 25 January 1930.The quarries operated internal railways of 2 ft (610 mm) gauge and were served by Glynrhonwy Siding off the LNWR's Caernarfon to Llanberis branch.Lower Glynrhonwy was acquired by the Air Ministry in 1939 for munitions storage. It occupied the site until 1961. During the Second World War the site generated two extra trains per day on some occasions. The railway siding was taken out of use on 18 December 1956.A 100 MW pumped storage project, marketed as a "quarry battery", received approval in 2017 and as at 2019 had reached the "detailed engineering design" stage.

Pontrhythallt was a railway station in the village of Pont Rhythallt, Gwynedd, Wales. This station opened in 1869 and closed for regular passenger services in 1930, but trains continued to pass through until the last goods train of all on 3 September 1964, which delivered a panel of lap fencing.The station was at the end of a nearly five mile climb from crossing the Afon Seiont on the southern edge of Caernarfon. Pontrhythallt's "Home" signal was the first since leaving the town, 5.75 miles (9.25 km) earlier.The 1939 Working timetable shows that some excursions made unadvertised stops at Pontrhythallt.The line was lifted in early 1965. The station survives as a private dwelling. The bridge over the Afon Rhythallt immediately next to the station has lost its original railway decking, but has been replaced with a footbridge.

Dinas Dinorwig, enclosing about a hectare of land, is the largest and best defended hillfort in Arfon, Wales. It is prominent in the landscape, overlooking a wide area. Its commanding position and the strength of its defences suggest that, until the Roman conquest, it was the outstanding centre of local power. It lies on a low ridge some 1 km south-east of the hamlet centre and 3.5 km from the Menai Strait. It has an inner stone wall, surrounded by two massive ramparts of earth and rubble (an unusual construction method in north Wales), some 12 meters wide at the base and 9 meters high. The ditches are deep and the outer ditch is some 4 meters wide, with a counterscarp surrounded in turn by another ditch also some 4 meters wide. One entrance through the inner wall is blocked by the ramparts, so the inner wall is thought to have been the first phase of construction. There is one depressed area, interpreted as the site of a hut, within the wall. To the north the outer ramparts have been flattened to produce the platform on which Pen Dinas farmhouse now stands. It is thought that it was part of the territory of the Ordovices tribe, and the element -orwig, -orweg has been derived from the tribal name Ordovices, so the name would mean Fort of the Ordovices. However this idea was rejected by the linguist Melville Richards for lack of an early record of a form *Orddwig.. (As "Dynorthveg" such a form is recorded in 1618.) In 77 CE, at some unknown location in the territory of the Ordovices, the Roman governor Agricola led his troops up a hill to a decisive victory. According to Tacitus, "He collected a force of veterans and a small body of auxiliaries; then as the Ordovices would not venture to descend into the plain, he put himself in front of the ranks to inspire all with the same courage against a common danger, and led his troops up a hill. The tribe was all but exterminated." He went on to conquer Anglesey, sending cavalry recruited in other parts of Britain swimming over the Menai Strait before the defenders of Anglesey were ready.

Clwt-y-bont is a village in Gwynedd, Wales, lying just to the south of Deiniolen. The two villages form one urban unit. Both were built in the early 19th century to house workers in the Dinorwig slate quarry, and both suffered when the quarry was closed in 1969.

Cei Llydan is an intermediate railway station on the Llanberis Lake Railway (LLR), located in Llanberis, Gwynedd, Wales.Most of the LLR was laid around 1970 on part of the trackbed of the closed and lifted Padarn Railway.

For thirty years Gilfach Ddu (LLR) was the new line's southern terminus, situated a short distance south of the site of the Padarn Railway's former workmen's station, also named Gilfach Ddu.

With this extension Gilfach Ddu (LLR) changed from a terminus to a through station. The line and station primarily serve tourists and railway enthusiasts, with Cei Llydan recommended for picnics and viewing the scenery.The station has one platform.
