Opened on the Ayr and Dalmellington Railway.The original Patna station was directly south of the Downieston bridge. There was a short platform on the west side of the line with a building. There was a signal box at the north end of the platform.
To the south was a goods yard, served from the north, on the west side. This had a goods shed.
The platform was relocated to south of the goods yard to Patna [2nd] when a loop was created using one of the goods yard sidings. The station building on the old platform remained.
The goods shed still stands.
The line is now single track but does not currently carry traffic (2018).
