Circumvesuviana (Italian pronunciation: [ˌtʃirkuɱvezuˈvjaːna]) is a railway network in the east of the Naples metropolitan area, previously run by a company of the same name, now operated by Ente Autonomo Volturno.
Electrically powered throughout, the system uses the narrow gauge of 950 mm (3 ft 1+3⁄8 in) and operates 142 km (88 mi) of route on six lines.
The network forms an important commercial artery, and provides services to the tourist destinations of Pompeii and Herculaneum.
A journey along the entirety of the longest route, the 47 km (29 mi) from Naples to Sorrento, takes about one hour.
The FE220 cars are usually coupled together to form a two- or three-car multiple units, painted white with red doors and ends.
