The idea to build an urban railway serving Salerno started in the 1980s and, between 1996 and 2004, several institutions signed and renewed agreements for the allocation of funds.

The works for the service, officially named "Metropolitan railway system of the Salerno conurbation",[1] started in early 2000s, and the line opened on 4 November 2013.

The planned extension will end at a western terminal of Via Monti (or Centro Storico Alto),[7] also located in Salerno.

The service, operated by "Minuetto" DMU trains (ALe 501/ALe 502), starts at about 6:21 am and ends at about 23:12.

The trains run, with some exceptions, each 30 minutes, for a total of 29 daily departures from each terminus (Salerno and Arechi).
