Line 6 of the Naples metro is an important part of the urban rail network,
carrying around 11% of all the city’s public transport passengers.
Ansaldo STS is the Naples local authority’s contractor for the design and
construction of all civil engineering and technological works on the whole of
the project.
Line 6 has the features of a light railway, as defined by the UNI UNIFER
8379 regulation.
The
automatic train control system is set up in an operational
central post, which also carries out the security, monitoring and information
functions and manages its operation and maintenance.The fail-safe
microprocessor-based system is configured according to the most
technologically-advanced standards used in recently-built metro systems in
Italy and abroad.
The trains are fitted with modern Automatic Train Protection (ATP) and
Automatic Train Operation (ATO) equipment, a wireless data communication system
and digital radio enabling the transmission of information with a high degree
of reliability.
The automated SCADA system monitors all power supply and station equipment,
guaranteeing rapid reconfigurations and advanced diagnostics capability and
maintenance of parts.Modern integrated telecommunications systems based on
fibre optics provide a network of link-ups via telephone, data and images,
which monitor the efficient operation of the system and provide information to
the public, thereby ensuring a high degree of passenger safety both in stations
and on trains.
The power supply system comprises primary distribution of 20 kV from three
electricity sub-stations that power the overhead line at 750V D/C. and activate
secondary distribution via MV/LV power cabinets equipped with diesel emergency
generators and a back-up (UPS) generator.
A huge floating concrete trackbed system will be installed to ensure that
noise and vibration are kept to a minimum - a fundamental requirement for a
transport system in a city environment, but one that has artistically and
historically valuable features.
Station and tunnel ventilation systems have been planned to ensure maximum
safety and reliability in dealing with emergency situations in the case of a
fire on the line or in the station in conjunction with the fire detection and
extinguishing systems.
The line, which will consist of around 6 km of double track, numbers eight
stations, decorated with contemporary artworks and designed by
internationally-renowned architects such as Siza, Kolloff, Siola, Lampugnani
and Podrecca: built from reclaimed surrounding land, it will create new
amenities for the public.
It will have a maximum transport capacity of 46 million passengers per year
and 154,000 passengers per day, with trains that can transport 570 passengers
every 4.5 minutes.
The first operational stretch between Mostra and Mergellina stations was
opened for public use on 4 February 2007.
In September 2007, a contract was signed for the design and construction of the
extension of the line from Mergellina to Municipio to be completed by 2013; the
new building sites are currently being started up.In November 2007, the plan
for the completion of the line from Mostra station to the depot/warehouse of
the former Arsenale Militare was approved and the funding allocated.
