In the last 50 years a new town of about 400,000 people is grown over the old maritime city. Efficient and rapid transportation way to make connected the “two level city ” was soon a challenge at the beginning of the last century So 4 smart urban funiculars were built. In 1925 a new underground double track railway going trough Naples town was built by Italian Railways. Thanks to this East-West link it has been possible to operate the first italian “Urban Underground railway Service”. It is not designed for specialized passengers traffic (Long distance and regional trains are allowed till today) Railway as a innovation for Naples PLANNING But Naples has been not only famous for the first Urban Underground railway link (with a drastic reduction of travelling time between Naples and Rome) but also because, during Borbonic Kingdom of “Two Sicilies”, in 1869, was built the “First Italian Railway”: NAPOLI-PORTICI with a length of about 6 km In 1970’s Naples Municipality Government realized thath the four funicolars and the Urban Underground Railway (after called Line 2 in the new Transportation Act) were not able to face up mass mobility need. 1976 line 1 first stone Naples railway network plan Train commuters bound for Naples in a weekday morning are about 60.000 Total public transport weekday trips in Naples (buses, trams, metros, urban railways,funicolars) are about 700,000* Line 1 Line 6 *Trips across borders are not included Railway situation scheme in Naples 20 years ago PLANNING NATIONAL RAILWAY from North REGIONAL RAILWAYS from South East Bound REGIONAL RAILWAYS from West Bound NATIONAL UNDERGROND RAILWAY LINK (SE-W through the town) It was also realized thath new lines able to intercept passengers interchange from suburban and urban transportation should be designed Piscinola Miano Regina Margherita Chiaiano - Marianella airport Central station Harbour LINEA 1 TRATTA VANVITELLI – PISCINOLADANTELINEALINEALINEA IN6 1 1 ESERCIZIO IN ESERCIZIO DAL DAL 2001 1993 TRATTALUNGHEZZATRATTA DANTE DELLA –TRATTA:CAPODICHINO CENTRO 8.3 DIREZIONALE KM -LINEA PISCINOLA 1 IN CORSO DI ESECUZIONE LUNGHEZZATRATTA DELLA CENTRO TRATTA: MOSTRA 4,9 KM LINEA – MERGELLINA 6 LUNGHEZZANUMERO NUMEROSTAZIONI: DELLATRATTA STAZIONI: TRATTA: CENTRO 595 KM DIREZIONALE 4 – CAPODICHINO LUNGHEZZA TRATTADELLA TRATTA: MERGELLINA 2,3 KM – MUNICIPIO NUMEROSTATO DI STAZIONI:STATO ATTUAZIONE: DI ATTUAZIONE: 5APERTA IN FASE ALL’ESERCIZIO DI APERTURA COMMERCIALE DI CANTIERI STATONUMERO DI ATTUAZIONE:LUNGHEZZA STAZIONI: DELLA APERTA TRATTA: 4 ALL’ESERCIZIO 3,4 KM COMMERCIALE LUNGHEZZADAL DELLA 19932001 TRATTA: PER L’ESTESA 3,2 KM VANVITELLI – COLLIMUSEO AMINEI STATOSTATO DI ATTUAZIONE: DINUMERO ATTUAZIONE: STAZIONI: LAVORI APERTA INCORSO 5ALL’ESERCIZIO COMMERCIALE DAL 2007 NUMERO STAZIONI:DAL 199527/3/2002 PER L’INTERA PER 4 L’INTERA ESTESA ESTESA STATO DI ATTUAZIONE: IN FASE DI PROGETTAZIONE STATO DI ATTUAZIONE:LUGLIO 2003 APERTURA IN FASE STAZIONE DI APERTURA MATERDEI CANTIERI Metronapoli 2011/15today network 2 metro lines 4 funicolars 2520 interchange links 5036 stationsstations 400,000160,000 passengerspassengers // dayday 10045ml ml passengers passengers / year/ year today line1 Route length 13.30 km Number of stations 14 Trip time between headways 23 min Commercial speed 34 km/h Gradient 5.5% Train running during rush hour 10 Actual headway 6 min Train Capacity 1,250 people Yearly passengers 2009 30 millions YearlyTrain km 2009 1 mln 2013 line1 Route length 18 km Number of stations 19 Trip time between headways 32 min Commercial speed 34 km/h Gradient 5.5% Train running during rush hour 28 Headway 2.5 min Yearly Passengers 2013 50 mln YearlyTrain km 2013 2.7 mln BUILDING Plan carry out Complex orographic constraints Discovery of archaeological ruins Big impact over scheduled building time and increase of costs BUILDING line1 Longitudinal Profile Policlinico station entrance: 275 m above sea level Salvator Rosa top rail level: The highest station entrance 45 m under ground Università The deepest top rail level Forecasted opening on next July Station entrance 5 m above sea level the lowest station entrance in operation under construction BUILDING line1 Schematic plan Average distance between stations 980 m Depot & viaduct Workshop Two single track tunnels under construction In operation 5 stations 14 stations 4,5 km double track 13,5 km double track Construction of station with a top of rail under sea level BUILDING Hydraulic milling machine utilized to build bulkhead station vertical border walls Construction of station with a top of rail under sea level BUILDING Reinforced concrete bulkhead for border vertical walls construction Construction of station with a top of rail under sea level BUILDING Water table Bulkhead carried out with reinforced concrete panels Pedestrian tunnels Station tunnels (platform and track) (escalators and stair way) Construction of station with a top of rail under sea level BUILDING Rectangular wells 20x45 m with a depth of about 35-50m .
