The Ardkinglas Railway was a narrow gauge estate railway built to serve the Ardkinglas Estate, former seat of Sir James Campbell, 2nd Baronet, of Ardkinglass on the shores of Loch Fyne.
The railway ran along the shore of the loch from a boat house at Caspian.
The railway was built as a transportation system for the estate and as a garden toy for the estate's 17th Laird George Livingston-Campbell-Callander. A single steam locomotive operated the line; rolling stock consisted of an open passenger carriage and several wagons.
The railway was dismantled around 1900 and the equipment sold. The boiler from the locomotive was still in situ on the beach at Tayvallich on Loch Sween until the early 1950s.
