Notes on the Merthyr Tydfil Tramroads – part 2

by Gwilym and John Griffiths

Cwm Cannaid Tramroad: We do not know when this tramroad was constructed. We would guess it was sometime around 1800-1814. Despite its name, the tramroad was built before the shaft of Cwm Cannaid Colliery was sunk. The track was shown clearly on the 1814 Ordnance Survey Map and on Robert Dawson’s 1832 Boundary Commission Map whereas the shafts of Cwm Cannaid Colliery were apparently sunk about 1845. The purpose of the tramroad was to relieve the inefficient old tub canal, or coal canal, sometimes called the Cyfarthfa Coal Canal, of the 1770s. The latter transported coal (and perhaps ironstone?) in two-ton tubs from levels (some suggested via dangerous leats) in Cwm Cannaid to Cyfarthfa Works: some say horse-drawn, others say hauled or pushed by men and women. The Cyfarthfa Coal Canal was closed around 1835, which gives an explanation of Cwm Cannaid Tramroad on Robert Dawson’s 1832 Boundary Commission Map.

The tramroad followed roughly the route of the old coal canal: the latter a twisting route, the former almost a straight line. It skirted Glyn Dyrys Ironstone Mine, a coal shaft below Lower Colliers Row, in front of Lower Colliers Row itself, Tir Wern Uchaf (where it crossed the canal twice), a link to Cwm y Glo Colliery and Ironstone Mine, Upper Colliers Row, Tir Heol Gerrig and hence to the coke ovens and yards above (to the west) of Cyfarthfa Works.

When Cwm Cannaid Pit was sunk in 1845, that became the terminus of the system. The 1901 Ordnance Survey Map named it ‘Cwm Pit Railway’, and the line linking it to ‘Gethin Railway’ was labelled ‘railway in course of construction’. We saw the remnants of these mines, canal and tramroad in the 1940s and 1950s, and often walked the old canal embankment, by then well wooded.

Again, industrial despoliation was reverting to nature: delicious wild strawberries on the old waste tipping, a nightingale singing by the disused and reed-covered canal reservoir, woodcock and common snipe, pied flycatchers and wood warblers, and numerous other birds; with wild orchids amongst the damp marshy vegetation with dragon-flies, damsel-flies, glow-worms and water-boatmen. We doubt if this still exists in the coniferous plantations which replaced them all in more recent years.

Dowlais Tramroad: This was constructed about 1792-93 to connect Dowlais Works with Pont y Storehouse near the Glamorgan Canal terminus, roughly near present-day Jackson’s Bridge. It gave Dowlais Works access to the then ‘recently’ constructed Glamorgan Canal. The route may well have followed initially the Morlais Quarry Tramroad from Dowlais via Gelli Faelog, keeping to the Gelli Faelog side of Nant Morlais. The 1793 extension from this tramroad is today represented by the main road and high pavement from Trevithick Street down to Pont Morlais and thence via the tunnel, formerly a bridge, into Bethesda Street to Jackson’s Bridge. Did the Glamorgan Canal Company pay the £1,100 for the construction of the tramroad (and Jackson’s Bridge) in lieu of the proposed linking canal from Merthyr Tudful to Dowlais?

Gethin Tramroad: This tramroad or railway linked Gethin Colliery (sunk between 1845 and 1849 and opened 1849) initially, and Castle Colliery later (1860s?), with Cyfarthfa Works, taking a route in between those of Cwm Cannaid Tramroad and Ynys Fach Tramroad. No tramroad was shown on the 1850 Tithe Map and Schedule. By 1886 the track left Castle Colliery, skirted the hillside west of the Glamorgan Canal between Furnace Row and Tir Pen Rhiw’r Onnen, through Gethin Colliery (with a link to pit-shaft No2), past Graig Cottage and a bridge over Nant Cannaid. At (the 1853) Cyfarthfa Crossing it curved northwestwards past Tir Wern Isaf and Tir Llwyn Celyn, looping under the 1868 Brecon and Merthyr Railway near Heol Gerrig, and thence to the coke yards.

By 1886 the route was upgraded to the GWR and Rhymney Railway as far as the Cyfarthfa Crossing. The 1876 six-inch Ordnance Survey Map showed the terminus for the ‘cwbs’ at the rear of Cyfarthfa Works. The 1901 Ordnance Survey Map called it ‘Gethin Railway’. Our grandfather used the railway to get to work at Castle Colliery, and we regularly used this route (then upgraded to a full railway) in the 1940s and 1950s on our daily journeys to and from school at Quakers Yard. One of us was on the last train to use this line before the viaduct between Quakers yard and Pont y Gwaith was found to be unsafe.

Gyrnos Quarry Tramroad: This was used to bring limestone from Gyrnos Quarry (Graig y Gyrnos) alongside Tâf Fechan, past the limekilns and coal yards, over Afon Tâf by Pont Cafnau to Cyfarthfa Works. We have no details of dates, but walked the route many times in the 1950s in search of dippers, kingfishers, grey wagtails and the rest. It was the first tramroad recorded in the 1805 list of John Jones and William Llywelyn: 1 mile 106 yards to Cyfarthfa Furnaces and just over 1¾ miles to the new Ynys Fach Furnaces. In view of the size of the quarry, it must have transported many tons of material.
