The first section of the Merthyr, Tredegar and Abergavenny Railway from Abergavenny to Brynmawr was opened on 29 September 1862.[2] The line was leased and operated by the London and North Western Railway (L&NWR) which acquired the smaller railway company on 30 June 1866.[3][4] On 1 March 1864, the line was extended from Brynmawr to Nantybwch.[5] A further 3-mile (4.8 km) extension to Rhymney Bridge through to Rhymney was jointly constructed by the L&NWR and the Rhymney Railway; the section to Rhymney Bridge was double-track whilst the Rhymney portion was single-track.[5] The joint line came into operation on 5 September 1871 when the junction was opened; the L&NWR had running powers over the Rhymney's line to Cardiff Docks.[5]
The station, which was at first known as Rumney Bridge,[6] opened to Rhymney services on 2 October 1871 and to L&NWR services on 1 January 1873.[6][7] It took its name from the bridge over the River Rhymney which was situated a short distance to the south-east; the nearest settlement was the village of Llechrhyd.[8] The station had three platform faces[9] and, as with the junction at Nantybwch, the signal box stood in the "V" of an island platform.[10] The two platforms serving the Abergavenny and Merthyr line had no passenger accommodation, although a brick station building stood on the Merthyr platform.[11] This structure has been described as "resembling a peasant's dwelling from the bleak wastes of northern China".[12] Rhymney Bridge itself was situated in a desolate location, with scant protection from the inclement weather provided by a weather-boarded footbridge linking the platforms.[13] The Rhymney branch platform was situated at a lower level to the main line platforms and was skirted by two goods loops which were useful for slow-moving goods trains.[14]
As a result of decline in the local industry and the costs of working the line between Abergavenny and Merthyr,[15] passenger services ended on 4 January 1958.[16] Services on the Rhymney branch had ceased on 23 September 1953[17][18] and goods facilities were withdrawn from Rhymney Bridge on 22 November 1954.[19] The last public service over the Merthyr line was an SLS railtour on 5 January 1958 hauled by LNWR 0-8-0 49121 and L&NWR Coal Tank No. 58926.[16][20] At Rhymney Bridge, a laurel wreath was placed on the smokebox door of No. 58926.[15][21] Official closure came on 6 January.[22][23][24]
