CTC signalling was commissioned in 1977, and freight services ceased in 1984.

Although the official start of the line is at Ikenotani, rail services from Naruto are considered outbound, with the reverse being inbound.

There is no through service to or from Takamatsu, forcing passengers to transfer at Ikenotani.

Moreover, connections to the Uzushio limited express service on the Kōtoku Line are poor, with waits of thirty minutes to an hour for a train.

Some trains are wanman driver-only operated, with others also having a conductor on board.
