Axonis is a non-proprietary integrated metro system, able to carry up to 45 000 passengers per hour per direction, available in a record time and designed to run on a viaduct but also at ground level and underground. Urbalis Fluence is the first urban signalling solution that is train centric and train-to-train communication enabling headways to be down to only one minute.
“Innovation is at the heart of our strategy. We remain focused on differentiating ourselves by state-of-art technologies and our strong expertise”, commented Henri Poupart-Lafarge, president of Alstom Transport. “With these new solutions, we will further strengthen our cooperation with cities to help them solve the challenges they are facing today: congestion, saturation, high pollution, and tight budgets”.
Axonis – a fully integrated metro solution available in a record time
Axonis is an elevated metro system able to transport from 15 to 45 000 passengers per hour per direction which run mainly on viaduct but can also run on ground level and tunnels. It is a non-proprietary system, allowing cities to increase their fleets and develop line extensions through a competitive bidding process. Axonis fits smoothly into the cityscape thanks to a narrow viaduct that follows the curves of the street (45m curve radius) allowing for greenery, shops etc. to be installed underneath.
The viaduct designed in partnership with a subsidiary of Bouygues (VSL) uses precast concrete girder boxes for technological simplicity, enabling them to be built by a large number of public works companies around the world. To limit construction nuisances, the viaduct superstructure is formed by concrete beams, cast off-site. Once the viaduct is elevated, concrete railway tracks will use Appitrack — an Alstom fast building method for trams and metro tracks that lays 150 metres of tracks per day compared with 20-50 metres when using traditional technology.
The train is Metropolis comprising two to five cars that can run at a speed of up to 80 km/hour on a gradient as high as 6 percent. For safe, easy evacuation, this metro opens up at both ends to allow passengers to walk to the next platform.
Energy consumption is limited as it is equipped with steel wheels, 100 percent motorised bogies and Hesop, a technology that enables full reuse of the kinetic energy generated by the train in breaking phases. Hence combination of these three elements reduces the traction energy required up to 40% compared with metro trains running on rubber wheels. The metro is driverless, equipped with the latest Alstom CBTC solution, Urbalis Fluence, which ensures maximum fluidity with minimum headways.
Axonis is designed for cities with high population density not yet equipped with metro systems or seeking to extend their current networks. It is also intended for cities with underground areas that have protected status as UNESCO World Heritage Sites or are difficult to access. Lastly, it can meet the needs of cities looking for a faster metro system at lower cost.
The system will be available to market by the end of the year 2013.
Urbalis Fluence – a breakthrough innovation through simplification
Urbalis Fluence, the new Alstom signalling solution, has been chosen by the Urban Community of Lille Metropole in France for Line 1 to be delivered in 2015.
