The outcome of these complex arrangements allowed the Midland to become the sole operator of the Brecon-Colbren-Ynys-y-Geinon-Swansea route, thus reducing the original main line between Colbren and Neath to the status of a branch. Until 1916 the Midland ran its trains beyond Brecon to Hereford, with parts of trains running directly to and from Worcester and Birmingham. Eventually these services were cut back to Brecon.
