Athy Co.Kildare is one of the larger towns served on the Great Southern & Western Railway's main line from Dublin to Waterford. Athy is the first stopping place for trains coming from Dublin. The station has up & down platforms, both of which see regular use by trains.The main station building is located on the up side and is positioned unusually at a higher elevation to the platform. It is large construction typical of the type found on the Waterford line. At the south end of the station is the large water tower, behind which is the former goods yard and shed. The nearby signal cabin which once controlled the junction with the branch to Ballylinan is now out of use.
The 12 mile Ballylinan branch was opened in 1918 to principally to serve the colliery at Wolfhill. The branch remained in use long after the colliery had ceased operated, finally closing to all traffic in April 1963. Today a stub of the branch remains in situ to serve the Tegral cement works in Athy, but this has been disused since 2005.
