D K Jones offering an introductory overview before turning the spotlight on the largest of the four ex-Taff Vale Railway sheds.
The Taff Vale Railway served both the Rhondda Fawr and Rhondda Fach. D K Jones offers an introductory railway overview to the locality before turning the spotlight on the largest of the TVR’s four sheds in the area and the duties covered.
The Rhondda is well known across the world due to the coal mining that took place mainly from 1809 to 1990 when Mardy Colliery in the Rhondda Fach closed, being the last coal mine in the Rhondda valleys. Perhaps less well known is that the Rhondda is in fact split into two separate valleys, the Rhondda Fawr (meaning big Rhondda) and Rhondda Fach (meaning small or little Rhondda). The source of both rivers is high up on the mountain, and the two rivers travel down the two valleys until they reach Porth (meaning gateway) where they converge and continue as one until meeting the River Taff at Pontypridd. Whilst the Rhondda starts at Pontypridd, Porth is technically the start of the Rhondda valleys.
With the expansion of coal production in the 19th century, the transportation of coal remained slow, via canals and roads at first, and it was a natural progression for railways to be constructed. Hereabouts, the prominent company in this aspect was the Taff Vale Railway (TVR), which originally built its line up the Rhondda Fawr to Dinas by 1841, and to Treherbert by August 1856. It then built a line up the Rhondda Fach from 1849, and eventually reached Maerdy by 1889. It is worth noting that in 1913 there were 53 pits working in the two valleys. However, it should be noted that the Taff Vale Railway did not have exclusivity in the Rhondda, as the Ely Valley Railway (leased to the Great Western Railway in 1861 and absorbed in 1903) constructed a line from Llantrisant via Tonyrefail, Penygraig and Gilfach Goch to exploit the coal production at Clydach Vale and its intermediate collieries, and locomotives for this line were provided by Llantrisant shed. The line from Coed Ely to the Rhondda, which was being used as a long siding, eventually closed when Cambrian Colliery ceased production on 31 March 1967.
Returning to the Taff Vale Railway story, the amount of traffic generated by coal production made servicing depots a necessity, and the TVR constructed engine sheds at Treherbert (1866) and Pwllyrhgebog (1863) in the Rhondda Fawr, and Ferndale (1866) in the Rhondda Fach, along with one at Coke Ovens, close to Pontypridd, in 1896. Treherbert, whilst almost at the limit of the Taff Vale Railway line up the Rhondda Fawr, was not the end of the line as it continued past Blaenrhondda, which was the first of the Rhondda & Swansea Bay Railway (R&SBR) stations, and through the 3,443 yard Rhondda tunnel via the R&SBR to link up with other rail companies and continue to Swansea via Aberavon. The line to these locations was eventually closed on 26 February 1968 following the closure of Rhondda tunnel. As would be expected in the South Wales valleys, there were quite severe gradients from Pontypridd to Treherbert and from Porth to Maerdy, which tested the skills of enginemen. However, the most severe was the Pwllyrhebog incline, which at its steepest was 1 in 13 and was also cable-worked.
Treherbert
The first engine shed at Treherbert was a stonebuilt semi-roundhouse with seven tracks, the design of which was extremely rare in South Wales. The facilities included a water tank, coal stage and a turntable. By Act of 1921 the TVR was amalgamated with the Great Western Railway from 1 January 1922 and the Treherbert semi-roundhouse was closed by the GWR in June 1931 and demolished to be replaced by a four-road straight shed of brick and asbestos. It was built under the Guarantees & Loan Act of 1929 and included a coal stage with a water tank over, it was provided with a turntable and was sited adjacent to the station. Coded 88F from nationalisation in 1948, the shed was closed by British Railways in March
1965 and subsequently demolished. A nearby site was utilised as a servicing point for dieselmultiple-units and is still in use today.
In Great Western and British Railways (Western Region) steam days the allocation of engines at Treherbert was generally of the 0-6-2T type, which was the well tried and tested design in South Wales. However, during the life of the shed it had an allocation of three TVR
‘H’ class 0-6-0Ts that were used at Pwllyrhebog, a few 0-6-0PTs, 2-6-2Ts and, for a short period, British Railways Standard 2-6-2Ts. Treherbert locomotive allocation: 1 January 1934 0-6-2T: Nos 152, 279, 365, 366, 368, 373, 378, 399, 409, 486, 5601, 5608, 5611, 5615, 5627, 5636, 5639, 5640, 5646, 5659, 5665, 5676, 5680, 5687, 5691, 5695, 5698
On Wednesday, 15 July 1953 the following engines were seen on shed – all 88F, unless shown otherwise.
0-6-0PT: Nos 8460, 8465, 8489, 9470

Operations
The main work for the shed was to provide motive power for moving coal – there were 31 freight turns – from the numerous collieries and for transporting it to the various distribution sidings and to the docks for export. The pick-up points down the
Rhondda Fawr included Blaenrhondda, Fernhill, Tydraw, Bute-Merthyr, Abergorki, Cwmparc, Maendy, Gelli, Llwynypia, Naval, Dinas, Hafod, Gyfeillion, Tymawr, Maritime and Penrhiw, before passing through Pontypridd, when hopefully the fireman could build his fire up for a non-stop run to its destination. Other duties included the quite intense passenger services of 28 turns (and with an increase during the summer timetable period) to Cardiff, Penarth and Barry, as well as a service west to Swansea. As with most South Wales valleys’ sheds, other work included colliery and chapel outings to Barry Island, Porthcawl and Aberavon Beach, along with specials to Ninian Park and Cardiff Arms Park for football and rugby matches respectively. Generally, the passenger turns were TA, TB, TD, and TH in the Cardiff direction, while TG worked to the west (see later). I have accessed various British Railways era documentation to offer a fuller backdrop to the operational range and requirements of the shed, although the practices were mostly long-standing.
‘No departure from the booked workings can be made without the authority of the Controller. It will be the duty of the Train Controllers to keep in touch with all points and control the workings, generally ensuring that traffic from collieries, works, and junctions are promptly cleared and worked efficiently, such as maximum capacity of trains, unnecessary shunting, and avoidance of overtime.’
In the winter of 1957/58 Treherbert shed was responsible for the following mineral and freight workings on weekdays; in all there were about 17 target workings. Standard timetable abbreviations are used here, such as MX (Mondays excepted) and SX (Saturdays excepted), MO (Mondays only), and weekdays were considered to be Monday to Saturday.

In regard to targets, it is interesting to note that in the early days of diesel-multipleunit working, certainly around March 1958, some of them carried the traditional target letters. By the late 1950s Treherbert shed had lost most of its steam-hauled passenger turns due to the introduction of diesel-multipleunits, but the mass of industrial installations still active in the vicinity and the relative late coming of dieselised goods services resulted in the need for a steam allocation through to 1965. Internal documents such as the Sectional Appendix included specific instructions that had to be adhered to by all staff to ensure maximum safety, and these examples were pertinent to the Treherbert operation.
Up trains for Tydraw and Blaenrhondda Colliery branches:
Up trains with thirty wagons or more for Tydraw and Blaenrhondda, instead of stopping at Rhondda and Swansea Bay Junction up home signal for the engine to be detached and run around its train, providing the signal is lowered, it must draw up to the main points so that the brake van will pass clear of the points leading from the up line to Bute Merthyr Colliery. Having come to a stand, the driver must await a signal from the guard before uncoupling the engine to run around. The Guard must secure the train before giving the driver the signal to uncouple and run around.
Propelling vehicles between R&SB Junction and Blaenrhondda stations:
Freight traffic, not exceeding five vehicles, may be propelled over the down line between R&SB Junction and Blaenrhondda. When it is necessary to propel vehicles into one of the down line sidings which is already occupied, the engine vehicles must be brought to a stand at the home signal, the points then to be set for the sidings to allow the traffic to be detached.
Running on wrong line between R&SB Junction and Blaenrhondda Junction signal boxes:
If necessary, an engine or engine and vehicles may run down the up line or up the down line between R&SB Junction and Blaenrhondda Signal Boxes. The guard or shunter in charge must communicate with the signalman and when authority is given for the movement will give the necessary hand signals to the driver.
Messrs T.C. Jones & Company’s Sidings, Cwmparc: These sidings are situated on the down side of the line and are connected by the up main by means of a trailing connection worked from Cwmparc Signal Box. WR engines are authorised to travel into one of the two sidings at the south end of the weighbridge but must proceed cautiously over the latter. Stopboards have been provided indicating the points to which WR engines may travel on the sidings north of the weighbridge.
Ynyswen Gound Frame:
This ground frame is situated on the down side of the down main line and works a trailing connection leading to Messrs. Polikoff ’s factory. There are two dead-end sidings for the exchange of traffic for the factory leading off the trailing connection to the down main line. Inward traffic must be detached in the sidings nearer to the down main line and outwards traffic picked up from the adjoining siding. Between these sidings and the firm’s premises the wagons will be transferred by means of a capstan.
Working of Trains R&SB Junction to Fernhill branch: Freight trains from R&SB Junction and Treherbert for the Fernhill Branch must be worked forward with a brake van next to the engine and to the rear of the train.
Llwynypia Upper Junction:
While wagons are being propelled into the Llwynypia Colliery Sidings, known as ‘The Gullet’, great care should be exercised as the radius of the curve is very tight.
Pitwood and other traffic for Naval Colliery: Guards of up trains having pitwood or other traffic for Naval Colliery Sidings must place the same on the sidings known as Naval Colliery Bridge Sidings and NOT in the empty road sidings.
Working of down trains, Pwllyrhebog signal box: Light engines, engines and vans, and freight trains consisting of less than 15 wagons must not be allowed to draw forward and stand at the down relief starting signal but must be held at the down home signal until permission for the train to enter the section has been received from the box in advance.
Assisting passenger trains in the rear in clear weather:
Treherbert to Blaencwm, distance 1 mile 56 chains, ruling gradient 1 in 54. When a passenger train booked to stop at Blaenrhondda requires assistance between Treherbert and Blaencwm the assisting engine must be coupled to the rear of the train between Treherbert and Blaenrhondda but then uncoupled at the latter and then assist to Blaencwm uncoupled. Trains not booked to stop at Blaenrhondda can be assisted in the rear from Treherbert to Blaencwm uncoupled.
