Colbren Junction was a railway station on the Neath and Brecon Railway. The station, which was near Coelbren, was completed at the same time as the Swansea Vale and Neath and Brecon Joint Railway opened a seven-mile branch from here to Ynysygeinon in 1873. It was a key junction in the networks operated by the Midland, Neath and Brecon, and Great Western railway companies.
