The first phase of Napoli Afragola Station – the new gateway to the south of Italy – has been inaugurated by prime minister Paolo Gentiloni. The new rail station at Napoli Afragola is designed as one of southern Italy’s key interchange stations serving four high speed intercity lines, three inter-regional lines and a local commuter line. In addition to the planned high speed rail services connecting Bari and Reggio Calabria with the north of Italy and Europe, by 2022 new rail infrastructure will create an important hub at Napoli Afragola serving the entire Campania region by integrating the southern expansion of Italy’s high-speed rail network with the Napoli Cancello line and the Circumvesuviana commuter railway extension.

Located at this major intersection within southern Italy’s rail network, Napoli Afragola connects the 15 million residents of Campania, Puglia, Molise, Calabria and Sicily in southern Italy with the national rail network in the north and the rest of Europe. It also enables goods and passengers from Europe and northern Italy to access the southern ports of Gioia Tauro, Taranto, Bari, Brindisi, Palermo and Augusta. To meet future demand for rail travel throughout the region (which has increased by 50% in the past decade) the Napoli Afragola station is within the new north/south rail corridor in the east of the greater Napoli metropolitan area that will be wholly integrated with local and regional rail services. Once all lines are operational, 32,700 passengers are expected to use the station each day (4,800 each morning and evening rush-hour) with a total of 84 express trains using the lines.

28 high-speed trains serving each direction will stop at Napoli Afragola every day, providing an express service in each direction every 30 minutes (40 minutes outside peak times), with approximately 700 passengers planned to alight or board from each platform. A further 200 regional and local train services will stop at Napoli Afragola, creating a key interchange within the national, regional and local rail networks. Public train services will begin on 11 June. Initially with 18 high-speed trains in each direction serving 10,000 passengers per day, services will increase to 28 trains in each direction as new infrastructure and further phases of the station come on line.

Located 12km north of Naples, Afragola station is also planned to serve its local communities of Acerra, Afragola, Caivano, Casalnuovo di Napoli, and Casoria that vary in population from 10,000 to 50,000 residents. Afragola will be an intermodal hub, relieving congestion in the city centre and will not replace the existing Napoli Centrale terminus. Designed as an urbanised public bridge connecting the communities on either side of the railway, the station is defined by the circulation routes of passengers, minimising distances for those embarking and alighting at Napoli Afragola as well those passengers connecting to different train services.

The design enlarges the public walkway over the eight railway tracks to such a degree that this walkway becomes the station’s main passenger concourse – a bridge housing all the services and facilities for departing, arriving and connecting passengers, with direct access to all platforms below. The paths of passengers have also determined the geometry of the spaces within. Large entrances at both ends of the station welcome and guide visitors up to the elevated public zones lined with shops and other amenities. Visitors from either side of the station meet in a central atrium above overlooked by cafes and restaurants.

This central atrium above the railway tracks is a much-needed new public space for Afragola and the main concourse where rail passengers descend to the platforms. The station has been constructed as a reinforced concrete base that supports an elevated concourse of steel ribs clad in Corian with a glazed roof. The concrete used within the station is a specific composition that provides optimum performance, with curved structural concrete elements built using technologies initially developed during the construction of the MAXXI Museum in Rome: wooden formwork replaced by prefabricated steel units, and double-curves realised with formwork created from CNC milled polystyrene models.

Designed as an extrusion of a trapezoid along a 450m curved path, the elevated concourse is made of 200 differently shaped steel ribs that are clad in Corian with a glazed roof. The main concourse of the station is oriented to benefit the building’s ecological sustainability. Integrated solar panels in the roof, combined with natural light and ventilation as well as ground source cooling/heating systems will enable the station to minimise energy consumption.

La Nuova Stazione Alta Velocità Napoli - Afragola, concepita da Zaha Hadid, si annuncia come una nuova porta per la città. Il progetto - fulcro del nuovo parco naturalistico-tecnologico mirato alla riqualificazione ed alla valorizzazione dell'area con laboratori ad alta tecnologia, centri per la sperimentazione agricola, attrezzature per lo sport e un grande centro espositivo - è basato su un ponte sopra ai binari, un percorso entro un volume di calcestruzzo e vetro, che assomma due principali funzioni: in primo luogo, rappresenta una passerella necessaria per il collegamento delle varie banchine, infine crea un effetto di continuità tra il territorio e la ferrovia, legando le due fasce del parco che si estendono sui lati dei binari.
Alle estremità est e ovest del ponte sono stati collocati i due accessi alla stazione, con il preciso scopo di convogliare i flussi dei viaggiatori, che attraversando le aree commerciali giungono alla sala passeggeri che rappresenta un nodo centrale. Essa è infatti pensata come un grande atrio, connesso visivamente con il paesaggio circostante attraverso ampie vetrate, dal quale si possono raggiungere la sovrastante area commerciale e i binari in basso.
Il sistema delle aperture è stato progettato secondo criteri bioclimatici: a sud nella stagione invernale la luce solare penetra direttamente attraverso le vetrate basse del centro passeggeri, in estate l'incidenza dei raggi solari sulle vetrate a sud è differente e questo consente una riduzione dell'irraggiamento pur restando l'apertura controllata verso la luce del nord.
La parte esterna della galleria è stata realizzata in materiale metallico con il sistema delle vetrate "a filo" con il rivestimento esterno.
