The line starts at Kellsthorpe Road and calls at Rolf's Castle before ending at Kirk Ronan. The line serves the harbour here, and ore and slate from Crovan's Gate are sent here. Kirk Ronan is known as a fishing port, so fish are unloaded here. A steamer service to Dublin is operated on Tuesdays and Fridays from Kirk Ronan, so tourists may use the railway as transportation to the port.
