[1] From February 1867, passenger trains started from Pendre instead, where the railway's permanent locomotive shed had been built.

The siding leading to the locomotive shed at Ty Dwr was removed,[2] but the water column was retained, and was still used until the early 1950s.

In 1955,[9] the tower was removed as the slate was needed to build a retaining wall at the site of a major landslip approximately 1 mile (1.6 km) south of Dolgoch.

[3] In 1976, the 0.75 miles (1.21 km)-long mineral extension to the foot of the Alltwyllt incline was re-opened for passenger services.

Abergynolwyn remains the principal station at the eastern end of the line as it has better passenger facilities than Nant Gwernol.

The base of the signal box was constructed out of slate blocks salvaged from derelict buildings in the Bryn Eglwys quarry.
