[2] The O&NR constructed a simple two-platform station southeast of Llanymynech, plus an adjacent goods yard, to enable shipping of locally quarried limestone, and created products of quick lime and lead.

To access its Nantmawr branch for similar mineral extraction purposes, it ran under the O&NR via a bridge south of the station, and the canal via an aqueduct.

[4] Designed, constructed and operated by the Royal Engineers, they built extensive additional service tracks along the 8.75 miles (14.08 km) of line from Maesbrook to the former Ford and Crossgate railway station, south of the River Severn.

This was one of two chemical warfare depots operated in co-operation with and guarded by the United States Army Air Forces, the second being in Shepton Mallet, Somerset.

[9] There were two signal boxes for Llanymynech, one immediately to the north, and one on the loopline junction south of the station, where the CR mainline became single track to Welshpool, just before crossing the River Vyrnwy.

There were two road bridges north of Llanymynech, making visibility of trains approaching from Oswestry potentially difficult from a standard height signal box.

Freight services continued to run on the Gobowen, Oswestry to Llynclys Junction section until 1988, to access the Llanyblodwel quarry on the Nantmawr branch.

[11] The station was demolished soon after the railway tracks were removed, relaid under tarmac as a heavy goods vehicle carpark, the abandoned state in which it remains today.

[2] It, together with a section south of Llynclys is part of an ambitious plan by the Cambrian Heritage Railways to restore services from Gobowen to the new Penygarreg Lane Halt and possibly beyond.
