This 68 million Euro investment is part of ATMs
development plan to increase safety and reliability on line 1.
The new signalling system will also allow the operator to
increase the frequency of trains by 30% and thus reduce the
time passengers have to wait for a train. Alstom will start the
renewal work early in 2007. During the works passenger service
will not be interrupted.
A non-stop radio transmission system - installed for the first
time in Italy, but which has already been proven by Alstom in
other countries will keep the trains in permanent
communication with the central control centre and will provide
real-time data on train speed and position in the metro system.
This will allow the Automatic Train Control (ATC) function to
operate immediately in the event of a failure. It is these
advanced safety functions that enable train frequency to be
increased in full safety.
The Automatic Train Control - ATC equipment and the system
software will be supplied by Alstoms R&D centre in
Meudon (France), where full system simulations and project
tests will be carried out.
Works coordination will be managed by the Alstoms
Bologna (Italy) from where station equipment such as Automatic
Control Centre - ACC and other signalling products will be
supplied. Bologna site will also coordinate all the maintenance
activities and will carry out some of software development.
ALSTOMs Savigliano (Italy) will plan, schedule and
carrying out the installation of new on-board systems, while
the Sesto San Giovanni (Italy) site will be the headquarters
for this project. Finally, the Verona site will supply the
radio and communication technology in this signalling system.
Alstom, the supplier of one out of four metros cars in the
world, built Singapore North -East metro line system the world
largest fully automatic heavy metro system. Among others metro
projects in progress, Alstom is currently installing
