Notes on the Merthyr Tydfil Tramroads – part 1

by Gwilym and John Griffiths

 TRAMROAD: According to the Oxford Concise English Dictionary, ‘tramroad’ is now an historical word: a road with wooden, stone or metal wheel-tracks; a ‘tramway’. Strictly speaking, ‘tramroad’ should be written ‘tram-road’ with a hyphen, but the spelling variation ‘tramroad’ has been used commonly in this district.  There were many tramroads constructed in this valley in so-called ‘historical’ times, though we can still recall many of them very well indeed and had much fun in our youth having rides on the trams.

Blaen Cannaid Tramroad: This tramroad linked several of the ironstone and coal levels, as well as later mines and collieries, in the hamlet of Gelli Deg to Cyfarthfa Works. The tramroad started at some ironstone levels about 900-1,000 feet above sea-level near Blaen Cannaid, not far from the site of the sixteenth century iron bloomery or small furnace. The route of the tramroad went between Pen y Cae and Pen y Coedcae, crossing the (unnamed?) stream which fed the small reservoir near Lower Colliers Row; and thence over Nant Cwm y Glo to Cwm y Glo Colliery and Ironstone Mine.

Thereafter it continued northwards to Coedcae Ironstone Mine, over Nant Cwm Pant Bach, across the road Heol Gerrig, linking with Cwm Cannaid Tramroad at the coke yards behind the furnaces at Cyfarthfa Works. We often walked the area in the 1940s and 1950s but recall nothing of note: merely grassed-over waste tipping, etc. What a pity?

Clyn Mil Tramroad: This tramroad went from Plymouth Works up the steep Clyn Mil Incline to the east, past Prospect House (where some distant cousins of ours, the Coles, lived in the 1940s) and Tir Clyn Mil Uchaf and its lime kiln (where our great-great grandparents, David and Mary Morgan, lived and died), and then turning south towards Clyn Mil Colliery and Ironstone Mine.

One link from the tramroad deviated further up the mountainside via Coedcae and the Clyn Mil Inclined Plane to several ‘unnamed’ ironstone levels and southwards to waste tipping on Gwern Las land. Another link went to ‘Waun’ Coal Level on Gwern Las property. Another link went to a clay pit on the south side of Clyn Mil Pond and another tramroad linked northwards to ‘New’ Pit (one shaft for coal and another for ironstone) close to Tir Cwm ‘Blacks’ and then on to the brickworks at Tre Beddau.

A very extensive network of lesser roads, some only temporary, covered the higher part of Tir Clyn Mil and Tir Wern Las and these were used either for transporting ironstone or waste tipping. We have no idea as to dates or any other details, but walked all of these routes on numerous occasions, long after the tramroad lines had been removed, in the 1940s and 1950s. It was a barren area then, with industry all gone, but the despoliation was gradually returning to nature again. Here were the homes of redstarts, wood warblers, even wood larks, with skylarks, meadow pipits and cuckoos towards the higher moorland portions. There is surprisingly little information in print about the Plymouth Works as far as we can trace.
