To avoid Walton's land, the branch had to be routed along the roads of Clipiau, which were too steep and narrow to allow a standard-gauge railway.

The quarry and tramway were sold at auction to Dennis Bradwell – the mayor of Congleton – and his brother Jacob.

[1]: 30–31 A Broad Vein quarry had operated at Maesygamfa, about 2 miles north of the tramway, in the 1860s, but on a very small scale.

They needed a transport link to get their produce to market and negotiated running rights over the Hendre Ddu Tramway with the Bradwells.

In October 1887, the quarry was connected to the Hendre-Ddu Tramway as part of the agreement between Walton, Davies and the Bradwells.

These were used for a variety of products, including billiard tables, floors, channels, window sills and grave markers.

When the strike ended in 1903, Penrhyn resumed production and many smaller quarries in Mid Wales shut down.

[1]: 71 During the First World War demand for timber grown in Britain rose rapidly as German raids significantly reduced imported supplies.

He ran the quarry and tramway with a very low budget, and trains stopped running in 1938, replaced by road lorries.

[12][page needed] A number of wagons from the Gartheiniog quarry were sold for use on the Meirion Mill Railway at Dinas Mawddwy in 1975.

Loaded wagons descended by gravity and uphill trains were hauled by horses or pushed by people.

An unknown number of wagons were fitted with petrol engines in the 1920s to provide the quarrymen with powered uphill travel.
