Arddleen was reclassified as a Halt in June 1954 when the original station building, which incorporated a small booking office and waiting room, was replaced by a simple wooden shelter.

The platform was constructed of fabricated stone block, in-filled and laid with a tarmac surface.Access to the halt was from a small lane that ran parallel to the towpath of the Montgomeryshire Canal and the railway.

Under the GWR Directive 'Halts Where Staff are Not Employed', it was the responsibility of the Station Master at Four Crosses in later years to visit the halts which were under his supervision to see that the premises were in proper condition and that notice boards, gates, lamps and shelters etc.

Arddleen Station (Halt) was closed to passengers on 18 January 1965 by the British Railways Board as part of the closure of the section from Oswestry to Buttington Junction.

The railway bridge just beyond the station, looking towards Pool Quay, was demolished and the cutting filled in during the 1980s as part of the straightening of the A483 road towards Welshpool.
