The Palermo metropolitan railway service is a commuter rail system operated by Trenitalia.

[1] The first section of the Palermo "metropolitana" was opened in 1990, a month before the beginning of Italia 90, the football World Cup.

The line used the tracks of the old Palermo – Trapani railway, running across the city until Notarbartolo station, and from there it followed the branch to the port, along which new stops were built.

In November 1993 a new branch was opened, on the tracks of the railway to Trapani, running diesel railcars type ALn 668.

[5] The metropolitan service was extended to Punta Raisi railway station, serving the Falcone Borsellino Airport.
