Congestion, lack of adequate mobility, environmental pollution and safety represent some of the most important challenges for urban transport today. Increasing urban transport capacity with more efficient signalling systems is at the crux of solving these issues.
For over 70 years, Alstom has been addressing such urban challenges and thereby is constantly upgrading its most proven CBTC* signalling solution: Urbalis.
In Mexico City, which has 22 million residents, Urbalis boosted capacity by up to 30% on its Linea Dorada (Gold Line) metro, shortening commuting time from 2 hours to 72 minutes—and reducing vehicle traffic which will eliminate 2,300 tonnes of CO2 emissions per year.

Beyond CBTC basics
Alstom proposes two CBTC solutions: Urbalis 400 and Urbalis Fluence. Both solutions capitalise on a common technological base (Urbalis) which is constantly being upgraded—and they offer the highest level of safety endorsed by official independent authorities.
Urbalis 400 represents the ideal CBTC solution for urban transit operators aiming to maximise performance and capacity, while requiring standard interlocking systems** for operational needs.
- High transport capacity and high availability for interlocking systems
- Management of mixed traffic (made of different rolling stock types) and interfacing signalling systems
The new Urbalis Fluence is the first train-centric CBTC. This innovative solution simplifies the complex route setting and interlocking functions, completely merging them into CBTC.
- Optimum train-centric architecture, with more on-board intelligence and direct train-to-train communication, leading to 20% less equipment and better performances
- Higher transport capacity with minimal headway (down to 60 seconds)
- Higher operational availability (24 hours) with extreme flexibility of train movements
- Optimal investment and LCC for all types of line configuration
** an interlocking system coordinates the track cross points and signals. It is designed so that it is impossible for a train to continue its route unless it is proven safe.
