 Both were built out of slate blocks, and the platform had a surface of slate chippings, edged with slate slabs (this slate was from the Bryn-Eglwys Quarry, brought to the site by rail).The station did not appear in Brawdshaw's Guide from November 1867 until July 1872 (the same time as was opened), which has mislead many sources to quote 1872 as its opening date.Some slate quarrying was carried out at the nearby Dolgoch quarry during the early years of the railway, and it is believed that a siding was provided here for them.
