Duffryn/ Troedyrhiw Continued

Duffryn/ TroedyrhiwBy the 1820’s the company was getting its coal from numerous mountainside levels and some shallow shafts. As iron output grew from the furnaces more coal was needed and deeper shafts were sunk. Along the line of the tramroad between the Plymouth Furnaces and Dyffryn the company sunk over ten pits. Shallow ones near the Plymouth works the deeper toward Dyffryn. Ultimately when the ironworks declined the collieries continued to produce large tonnages of coal. Coking and house coal was mined from the Saron and Taldwyn levels, good dry-steam coal from the deeper seams in Graig and South Duffryn Pits which continued to work until the 1930’s.

There have been many changes along the route of the Tramroad between Pentrebach and Troedyrhiw as a result of landscaping which took place in the early 1970’s. These erased the last ruins of ironworks and collieries and provided a large plateau, on which the Linde factory has been constructed. The course of the tramroad is regained on entering Troedyrhiw, running to the rear of Chapel Street and along Mount Pleasant. These cottages, most modernized, are some of the oldest now left in the Merthyr area and originally would have provided accommodation for colliers and ironworkers.

To the west across the valley, we can also see the huge tip (now landscaped), the only remains of the Castle Colliery that belonged to the Cyfarthfa ironworks. Sunk in 1867 the single shaft reached a depth of over 400metres to mine the excellent quality seams on the west side of the Taff. At King’s Hill the Tramroad would have crossed the Turnpike Road before passing in front of an ancient stone built cottage, which is still standing. Unfortunately this part of its course is in private ownership so the modern route has been forced to follow the pathway alongside the road, leaving it at a point near to the site of Dan-y-deri Colliery.
