Penrhyn Quarry Railway

Llandegai Tramway

The earliest predecessor to the Penrhyn Quarry Railway was the one mile (1.6 km) long 2 ft ¹⁄₂ in (622 mm) gauge Llandegai Tramway which was built in 1798. The tramway was connected to a local flint mill that ground clay and chert into flints. These were transported to Porth Penrhyn on the coast by the tramway,[6] which was one of the earliest overground railways in Britain. It included two balanced gravity inclines one from the floor of the Cegin valley near Llandegai to the hills above Bangor, the other dropping from there to the mill. Both inclines used vertically mounted winding drums.

The success of the Llandegai Tramway encouraged the owners of the Penrhyn quarry to consider a similar tramway from their slate quarry to Porth Penrhyn. The plan subsumed the existing tramway into a longer railroad that connected Bethesda to the sea.

Construction started on 2 September 1800, relaying and extending the Llandegai Tramway, with the first slate train traveling on 25 June 1801. The new railway was also 1 ft 11 ¹⁄₂ in (597 mm) gauge. The connection to the Llandegai flint mill continued to be used until 1831. The railroad was operated by horse power along with gravity and three balanced inclines – "Port" (sometimes called "Marchogion") near Llandegai, which was inherited from the Llandegai Tramway, "Dinas" north east of Tregarth and "Cilgeraint" a short distance north of Coed-y-Parc workshops in Bethesda. The longest extended for 220 yards. With hindsight this seems hard work, but the overall gain was remarkable, shown not least by the cost of transport falling from 4 shillings per ton to 1 shilling[7]

By the early 1870s the Penrhyn Quarry Railway was no longer able to keep up with the output of the Penrhyn quarry. By 1874 the decision had been made to replace the railroad with a steam locomotive worked railway without rope-hauled inclines. Steam locomotives had already been introduced with great success on the quarry's internal railway system and at the nearby Dinorwic Quarry. The Ffestiniog Railway's example had shown that running a 2 ft gauge line for several miles from quarry to sea was perfectly feasible, and that company's Charles Easton Spooner was retained to survey and map possible routes to the port. The Penrhyn directors saw every reason not to follow the Padarn Railway's example and build a main line built to a gauge of 4 ft, joining lines in its quarries to lines in its dock both at a much narrower gauge. All Penrhyn tracks were of the same narrow gauge, so no costly and inefficient internal trans-shipments were needed.[8] At the end of 1875 the first "mainline" locomotive was delivered to Port Penrhyn and moved to the quarry workshops at Coed y Parc. The railroad was converted into the new railway in five stages from 1877 to 1878.

Penrhyn Quarry Railway

The first locomotives used on the new railway were three De Winton's with horizontal boilers. Although successful, these locomotives were not powerful enough for the substantial traffic that passed down the line. In 1882 the railway ordered 'Charles', a large 0-4-0ST from Hunslet. Charles proved very successful and was followed by 'Blanche' and 'Linda' in 1893 to the same basic design. These locomotives were the mainstay of the railway for the rest of its life.[9]

There was a significant demand for building materials after the First World War, as Britain recovered from the conflict and many new houses were built to replace slums. The slate industry had been largely mothballed during the conflict, but now found itself in a boom period. Shortly after the war, the quarry began producing Fullersite - ground slate waste - which was shipped in large quantities along the railway. In 1924, with traffic continuing the rise, three additional Baldwin locomotives were purchased. These had been built for war use by the United States Army Transport Corp, and were refurbished before being sold to the railway, but were not successful, and after three years of intermittent use they were put aside. [9]

Immediately after the Second World War, there was a short boom in demand for Welsh slate, to meet reconstruction needs throughout the United Kingdom. However this proved to be a short-lived period of success, and cheap foreign imports of slate and new man-made roofing materials quickly began to eat into the market for the higher-quality and more expensive Penrhyn product. A steady decline in traffic through the 1950s and growth in the use of roads for transporting slates direct from the quarry to market meant the end of the railway was inevitable. In June 1962, the last slate train ran, though a few unofficial trips were run as late as the summer of 1963.[10]

Heading seawards (northwards) from the quarry at Bethesda the first (Cilgeraint) incline was bypassed by building an almost parallel straight line at a gentler end-to-end gradient whose foot was some distance north of the foot of the incline. A similar approach was not feasible for the other two inclines, so the traditional approach was taken – to increase the length of the line to spread the grade. The old route was retained to the head of the Dinas Incline where the new line swung through 180 degrees in a horseshoe bend, thereby changing from heading northeast to southwest. It then swung past a new halt at Tregarth before swinging northwards again past a new halt at Felin Hen, whereafter the line headed more or less straight for Port Penrhyn, meeting the original alignment below the foot of the Marchogion Incline.

The main line's primary purpose was to carry finished slates and Fullersite (powdered slate)[11][12] to Port Penrhyn where they were loaded onto ships or, from February 1852 when the Chester and Holyhead Railway opened its Port Penrhyn Branch,[13][14] onto standard gauge trains.[15] The ships and standard gauge trains took the products to national and international markets. Secondary traffic consisted of slate materials which were finished at workshops at Port Penrhyn into bitumen blocks and, notably, writing slates on which the port had a British near-monopoly in the 1930s.[16][17] Paying backloads were few, but sufficient coal was brought from the port to the quarries to warrant the company buying a fleet of 50 coal wagons. The line also carried internal user traffic such as spare parts. The intermixing of standard and narrow gauge lines at the port produced some remarkable pointwork.[18][19]

Lord Penrhyn had his own saloon coach,[20] which has survived into preservation.[21] An example of the second type of passenger vehicle – an Incline Carriage – has survived in the Penrhyn Castle Railway Museum. It was intended for conveying visitors and guests round the quarry itself, having inclined seats for comfort when travelling up and down inclines between levels.[22]

Workmen's trains were provided,[23] along with specials for visitors and dignitaries, but the railway never provided a public passenger service.[24] The quarrymen's carriages were unsprung and open to the elements, having neither roofs nor doors.[25] In the frequent event of rain and cold passengers usually covered themselves with sacks to keep out the worst. Each carriage could carry 24 quarrymen "at a pinch". The carriages resembled enlarged versions of many used on garden railways in fine weather.[26] 16 of these were built in two batches between 1878 and 1908, each bore a single letter in the series A to P. The service was withdrawn on 9 February 1951,[27] rendering the carriages redundant. Seven survived, six were given or sold to the Talyllyn Railway where they were modified[28] or cannibalised to such an extent that no Penrhyn bodies survive there. The seventh survivor was acquired by the Penrhyn Castle Railway Museum,[29] where it remained on view in 2016. Contradicting this to a degree is the Moseley Railway Trust which has carriage "O", which came into their hands after a long tour of various preservation sites, starting with Bressingham Steam and Gardens.[30] The trust has also built a replica of carriage "H".[31]
