The 6km line links Salerno Central with some of the city's most densely populated districts, serving Torrione, Pastena, Mercatello, Arbostella before terminating at Arechi.

The project, which involved constructing a new electrified single-track line alongside the Southern Tyrrhenian main line, was initially proposed in the 1980s but there was little progress until 1996, when a contract was awarded to Italferr to carry out detailed design.

Prior to the introduction of the full service with the December timetable change, an interim service of 29 trains per day is operating between 0610 and 2215. A single fare costs €1.30 and the line is covered by the Unico Campania regional fare system.

Extensions of the line to Battibaglia and Salerno airport are planned, and the city is also proposing a second north-south suburban line, which would involve electrifying the existing Salerno – Baronissi line.
