Because of high construction cost due to geography there is single track between Kashima and Nagasaki, and because it runs along a complicated coast there are a lot of curves.

The branch of the Nagasaki Main Line which existed before the opening of the new line and runs from Kikitsu to Urakami by way of Nagayo is called the old line (旧線). Before the opening of the new line, express and limited express lines ran on this track. You can see vestiges of this at Michinō and other stations on the old line.

The branch of the Nagasaki Main Line that is electrified, runs through Nagasaki Tunnel, and goes from Isahaya to Urakami by way of Ichinuno is called the new line (新線).
