all full of energy for this one after a good nights sleep, here is part one of i think maybe 3 videos from one of Wales most popular mines, here is some info on it from Wikipedia
Maenofferen was first worked for slate by men from the nearby Diphwys quarry shortly after 1800. By 1848 slate was being shipped via the Ffestiniog Railway, but traffic on the railway ceased in 1850. In 1857 traffic resumed briefly and apart from a gap in 1865, a steady flow of slate was dispatched via the railway. The initial quarry on the site was known as the David Jones quarry which was the highest and most easterly of what became the extensive Maenofferen complex.
In 1861 the Maenofferen Slate Quarry Co. Ltd. was incorporated, led by Sir William Fothergill Cooke and Mr. Veasey.[3] The quarry produced around 400 tons of slate that year. The company leased a wharf at Porthmadog in 1862 and shipped 181 tons of finished slate over the Ffestiniog Railway the following year.
During the nineteenth century the quarry flourished and expanded, extending its workings underground and further downhill towards Blaenau Ffestiniog. By 1897 it employed 429 people with almost half of those working underground. The Ffestiniog Railway remained the quarry's major transport outlet for its products, but there was no direct connection from it to the Ffestiniog's terminus at Duffws. Instead slate was sent via the Rhiwbach Tramway which ran through the quarry. This incurred extra shipping costs that rival quarries did not have to bear.
In 1908 the company leased wharf space at Minffordd, installing turntables and siding to allow finished slates to be transshipped to the standard gauge railway there.
In 1920 the company solved its high shipping costs by building a new incline connecting its mill to the Votty & Bowydd quarry and reaching agreement to ship its products via that company's incline connection to the Ffestiniog Railway at Duffws.
