Metropolitan Railway. On 30 June 1909 the Light Railway Order was confirmed by the Board of Trade, and the passenger service was inaugurated on 2 August 1909. As well as the main line, the branch to Ty Coch was included. The main line operation was as far as Pontyberem, although a petition had been received from residents at Cwm Mawr for a service; the incremental cost of that would have been £4,000, and there were formidable gradients on that section. Public stations were at Burry Port (immediately south of the GWR Pembrey & Burry Port station), Pembrey, Pinged, Trimsaran Road, Pontnewydd (renamed Glyn Abbey in 1910), Pontyates, Ponthenry railway station, and Pontyberem. The possibility of extension of passenger operation to Cwm Mawr was revisited; considerable new earthworks were required to ease the gradient to 1 in 40, and an estimate of £4,844 for the work was arrived at. The proposal was ratified and the necessary Light Railway Order was confirmed by the Board of Trade on 4 October 1911. Three former London and South Western Railway six-wheel coaches were acquired, to be converted to four-wheelers; Cwm Mawr was to be supplied with water and electricity from the New Dynant Anthracite Colliery company. Passenger services started on 29 January 1913. Another halt was opened to serve Glynhebog Colliery, probably in 1898 when the passenger service was extended to Cwmmawr. After the introduction of authorized passenger trains from 2 August 1909 the workmen's trains on the main line became regular service trains; however, the Ponthenry and Pentremawr Colliery halts for the collieries were not shown in the public timetable, and only certain trains stopped there. The halt at Trimsaran Road became a regular stopping place, and additional halts were opened to serve other collieries at Trimsaran Junction and Carway Colliery Sidings (between Glyn Abbey and Pontyates). Workmen's trains continued to run to Ty-coch on the Kidwelly branch but these were not shown in the public timetable. The twentieth century In the first years of the twentieth century the production of anthracite in the area served by the railway increased very considerably, and the fortunes and profitability of the company rose correspondingly. 10% dividends were paid on ordinary shares in certain years in the period. At the end of 1903 the Gwendraeth Valleys Railway Company approached the BP&GVR with the intention of selling their concern; the BP&GVR negotiated but an acceptable price could
