Miami: Modernising the iconic Metro mover system, which has been serving passengers for 35 years, optimising operations with Urbalis Flo CBTC signalling

High reliability and safety 

The Urbalis Flo solution has been designed to meet the most stringent safety, reliability, maintainability, and availability requirements. The technology also allows a high degree of operating flexibility to accommodate peak passenger demands and can connect with future mobility projects. 

Delivering capacity

Communications-based train control (CBTC) is tackling the capacity challenge worldwide. It provides advantages for safe and cost-effective infrastructure management for the full range of mass transit systems and for all grades of automation. 

CBTC reduces the headway between vehicles, enabling trains to run closer to each other compared to a fixed block system. Urbalis Flo can be used as an overlay to upgrade existing systems or for new greenfield lines.

  • Innovia monorail Bangkok Pink and Yellow line, Thailand

    In 2017, Alstom was awarded a contract to deliver fully automated monorail systems for the Pink (34.5km) and Yellow (30.4km) lines in Bangkok. The Yellow Line started service in June 2023 reducing journey time to a third in the heavily congested area of the city.

  • Innovia monorail São Paulo, Brazil

    In 2010, Alstom was awarded a contract for a 24‑km monorail system in São Paulo. The 54 seven‑car driverless Innovia trains, equipped with Cityflo 650, will link 17 stations in 50 minutes—halving the two‑hour car journey for up to 600,000 passengers daily. Phase 1 opened in 2014.

  • Innovia APM Los Angeles International Airport, USA

    In June 2018, Alstom and a consortium partner were chosen to design, build and finance, operate and maintain a new automated people mover system.

Ensuring performance and efficiency 

The first ever radio-based, moving block CBTC system, Urbalis Flo, was first installed in 2003 on the APM system at San Francisco International Airport. Today, the solution has been adopted on more than 30 rail lines worldwide, with another 30 under implementation. 
Thanks to its advanced features, such as driverless technology and regenerative braking, the system is extremely efficient to operate. Service is frequent, reliable and safe, meaning more comfort for passengers and more revenue for cities.
