There are two metro lines in Naples: line 1 and line 2. Line 1 is the newer and faster line.
Naples's Metro (Subway) Line 1
Line 1 is known as the “Metropolitana dell’arte”, or art subway, as the stations have been decorated by contemporary artists; the Toledo station is perhaps the most striking. Though the stations are modern, the service itself leaves something to be desired as trains only run about every 10 minutes and are very crowded at rush hour.
The subway line 1 (Metropolitana Linea 1) in Naples runs from Piazza Garibaldi (the Napoli Centrale train station) to Piscinola, crossing the entire historic center and the hilly Vomero neighborhood. Trains run from 6:20AM to 11PM; on Saturdays, trains run until 1AM.
Tickets for metro line 1 can be used on all ANM transportation, including buses and trams.
The “art stations” decorated by contemporary artists are Garibaldi, Università, Municipio, Toledo, Dante, Materdei, Salvator Rosa, Quattro Giornate, Vanvitelli, Rione Alto, and Museo.
Naples's Metro (Subway) Line 2
Line 2 was once the only underground metro in Naples and, as opposed to Line 1, uses rail cars. The route runs between Pozzuoli and San Giovanni a Teduccio and is used primarily to reach the Flegrea or Piazza Amedeo (Via dei Mille and Corso Vittorio Emanuele) areas. Trains run every 8 minutes from 5:20AM to 11:20PM. Line 2 and Line 1 cross at Piazza Garibaldi and Piazza Cavour.
The 90-minute pass is good for line 2, line 1, and ANM buses and trams.
The Cumana Railway
The Cumana is a local rail line that runs between downtown Naples and a number of neighborhoods and towns in the outlying Phlegraean Fields. This is where the nearest beaches are located, which can be quite crowded in summer.
The terminal in downtown Naples is the Montesanto station in the Pignasecca neighborhood, while the terminal in the Phlegraean Fields is Torregaveta. It takes about 40 minutes to ride the rail line from beginning to end, and ticket prices vary according to the length of ride; it costs EUR 2.60 to reach Torregaveta from Naples.
Schedule: trains depart every 10 minutes in summer and every 30 minutes in winter, from 5:30 a.m. to 10:30 p.m.
Ticket (single ride): EUR 2.60
