Hereford, Hay and Brecon Railway

The Hereford, Hay and Brecon Railway (HH&BR) was a railway company that built a line between Hereford in England and a junction with the Mid-Wales Railway at Three Cocks Junction. It opened its line in stages from 1862 to 1864. It never had enough money to operate properly, but the Midland Railway saw it as a means of reaching Swansea, and from 1869 the Midland Railway was given exclusive running powers over the HH&BR. There was then a long-running dispute over whether the Midland inherited rights of access previously granted to the HH&BR.

Although the Midland used the route for goods access to and from Swansea, the line was never developed as a trunk route. As a rural line it failed to achieve commercial success and in 1962 the passenger service was withdrawn, followed by total closure in 1964.
