011983E 49 Talyllyn West junction
Talyllyn Junction was a railway junction located 4 mi (6.4 km) east of Brecon, Powys created where the Brecon and Merthyr Railway from the south met the Mid-Wales Railway from the north-east.
The northern side of the triangle followed the course of the 1816 Hay Railway, a tram-road worked by horses connecting the town of Hay with the Brecknock and Abergavenny Canal at Brecon. At the western end lay a tunnel which required widening and deepening for use by standard gauge trains.
