Athy railway station opened on 4 August 1846 by the Great Southern and Western Railway. Córas Iompair Éireann took over with the nationalisation of the railways under the Transport Act 1944, and is operated by Iarnród Éireann since 1986.
The single track north and south of the station splits to provide two platforms. Platform 1, next to the station building, car park and pedestrian entrance, is used where possible for passenger services. only when two trains are in the station simultaneously is Platform 2 used.
A siding at the southern end of the station is all that remains of the line to Wolfhill.
In 2004, with EU funding support, the mechanical signalling system was replaced and the signal box demolished in 2007 when the platforms were extended to accommodate longer trains.
