The project aims to provide a comprehensive overview of the Metropolis train, highlighting its role in shaping the future of urban rail transit.

Design and Features

The Alstom Metropolis train boasts a modular design, adaptable to various operational requirements. Available in small, medium, and wide body configurations, it can be configured as a two- to six-car trainset, catering to varying passenger capacity needs. Its construction utilizes either aluminum or stainless steel car bodies, coupled with steel or rubber-tired wheels depending on the client’s specifications and track infrastructure. The trains are designed for speeds of up to 90 km/h. Passenger comfort is paramount, with features including wide and customizable doors, spacious gangways, modular seating arrangements optimized for passenger flow, and dedicated spaces for passengers with disabilities. A robust onboard Ethernet backbone provides high-bandwidth communication for security and various subsystems, including optional public address and passenger information systems. An integrated Information and Communication Technology (ICT) system enhances passenger information and entertainment, while also integrating with security and communications subsystems. Real-time train condition monitoring is provided via the TrainTracer online tool, transmitting data to the depot and Operational Control Centre (OCC).

Automation and Technology

The Metropolis platform is at the forefront of automated train operation. It is designed to be fully compatible with unattended train operation (UTO) systems, enhancing efficiency and reducing operational costs. The train’s propulsion system uses the Onix IGBT (Insulated Gate Bipolar Transistor) traction system, integrating a standard IGBT inverter system, and it incorporates regenerative braking to minimize energy consumption. Furthermore, the Metropolis train seamlessly integrates with advanced signaling systems, including Communications-Based Train Control (CBTC), allowing for precise train control and increased line capacity.

Global Deployments and Projects

The Metropolis train’s success is evident in its extensive global deployment. It has been adopted by over 50 operators worldwide, with more than 4,000 cars currently in service. Notable projects include the North West Rail Link in Australia (the nation’s first fully automated rail network), the Chennai Metro system in India, lines within the Amsterdam metro, and various lines within the Buenos Aires metro system, to name a few. These projects demonstrate the train’s adaptability to diverse environments and operational needs.
