Dati ISTAT Population and transportation growth PLANNING
Early times eruptions gave rise to particular orography of Naples city with large hills (about 300 m high) very close to the sea. 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*

It was also realized thath new lines able to intercept passengers interchange from suburban and urban transportation should be designed Piscinola

Materdei station Operation & OPERATING Maintenance Issues
ITALIAN TRANSPORTATION SAFETY LAWS EXPRESS A FUNDAMENTAL REQUIREMENT TO AIM TOWARDS A HIGH SAFETY RISK REDUCTION
STATEMENT A Since 1998 in Italy there has been a strict and severe legislation about project rules for risk fire reduction and passenger evacuation from an underground metro line.
STATEMENT B Moreover, lifts and escalators operating such a link for public transportation (f.e. inside railway stations, inside airport, in a square, linking two streets) require an uninterrupted monitoring by skilled rescue personnel, particularly close to these equipments when there is a significant drop like in metro stations. The same strict legislation about lifts and escalators operating for public transportation require preventive scheduled checks every three months and preventive huge scheduled renewals every five years Operation & OPERATING Maintenance Issues
CONSEQUENTLY, CONSTRUCTION AND OPERATING & MAINTENANCE COSTS OF NEW METRO LINES ARE HIGHER THAN EXISTING OLD LINES AND, GENERALLY, MORE EXPENSIVE THAN IN OTHER EUROPEAN COUNTRIES WITHOUT SO SEVERE SAFETY LEGISLATION
MANDATORY STATION FIRE EQUIPMENTS : •Smoke detectors linked to Remote Control Unit able to send alarm to Station Control Room located in station mezzanine; •Water barriers -starting in automatic and manual mode – bordering every walkway exit from platforms to stairways •Reversible fans able to assure smoke evacuation under platforms, in case of fire event inside a train •Specialized water pipes for exclusive use inside metro stations by fire rescue personnel OPERATING Safety equipments
Platform automatic water Emergency barriers working for escape scheduled check platform along viaducts and tunnels Station operation OPERATING organization During passenger service it’s mandatory to have skilled agent in each station Control Room: Above all, he is responsible to manage equipments for passengers station transit and for passengers evacuation during an emergency. Yet, he is responsible for Customer information, particularly during train service disruptions

Easy and rapid passenger boarding and alighting thanks to train floor/platform alignment and good doors density per side.
DURING RUSH HOURS THIS IS EXCELLENT FOR DWELL TIME REDUCTION IN MASS TRANSIT TRANSPORT Peculiar Maintenance for station artworks OPERATING
The maintenance and restoration necessary are realized from the Academy with the involvement of "yard-school" students and of the trainees of the Contemporary Art Maintenance and Restoration Course. Peculiar Maintenance for permanent way OPERATING
High gradient (5.5%)and narrow curves (200 m) has been forced in our line.Therefore we need a special yearly track maintenance (rail reprofiling and grinding) and on board lubrication management Final Considerations
CONSTRUCTION AND OPERATION COSTS DEPEND FROM OWNER AUTHORITY DECISIONS IN ORDER
•TO ACCEPT A LEVEL FOR EACH INNATE RISK COMING FROM UNDERGROUND RAILWAY SERVICE ASSESSMENT - RULES TO BE STATED (Signalling technology, Fire Emergency along tunnels, Passengers emergency inside lifts, Handiccaped and blind people access availability); •TO FIX A CUSTOMER SERVICE RATE (security, passenger information during disruptions) •TO TAKE THE MOST OF THE OPPORTUNITY OF THIS HUGE INVESTMENT TO CREATE EXCELLENT TOURISTIC CITY IMAGE (ARTSTATION, VALUABLE BUILDING MATERIALS, PRECIOUS ARCHITECTURAL SOLUTIONS) AND INCREASE VALUE FOR SURROUNDING REAL ESTATE AND INCREASE BUSINESS FOR CITY TOURISTIC OPERATORS DONOSTIALDEA´S METRO GETS MOVING
