The current station was initially named Hengoed & Maesycwmmer when opened by the Rhymney Railway in 1858. Then on railway grouping into the Great Western Railway in 1923 it became known as Hengoed Low Level to avoid confusion.[1]
Hengoed High Level railway station
Immediately adjacent, and crossing Hengoed Low Level was another station which originally shared the name Hengoed & Maesycwmmer, serving the Taff Vale Extension from Pontypool to Quakers Yard (and ultimately Neath). This station was renamed in 1923 to Hengoed High Level.[1] The High Level station was immediately at the end of the Hengoed Viaduct, which carried the line across the Rhymney valley to Maesycwmmer. It was closed in June 1964. The line is disused, but the viaduct has been restored and is now part of the National Cycle Network. Some remains of the platforms have also been preserved.
The Monday to Saturday daytime service pattern is four trains an hour southbound to Cardiff Central: three continue to Barry Island and one to Bridgend. Northbound four trains an hour run to Bargoed with two of those continuing to Rhymney. The frequency decreases in the evening.
