The signal box (formerly one of three at the station and dating from 1892)[2] is the only surviving example on the HoW route and since 1986, it has supervised the entire line north of here to Craven Arms using a system of working known as No Signalman Token Remote (NSTR).

The Llanelly Railway first reached the village as long ago as 1839, continuing eastwards to Garnant following within a year and the main line being extended to Duffryn (the current Ammanford) in May 1841.

The main building is Grade II-listed and dates from 1857, but had been disused since the 1960s - it was restored and refurbished by Network Rail (with assistance from the Railway Heritage Trust and the local community) in 2013-14.

[8] Step-free access is available from the level crossing at the north end - this still has manually-operated metal gates rather than the automatic barriers used elsewhere on the line.

[9] The old Amman Valley branch line through Ammanford and Gwaun-cae-Gurwen which joined here to the other side of the current platform was closed in its entirety along with the yard after the closure of Abernant Colliery in 1988.
