Smartlock range: Intelligent and effective interlocking for train protection

Intelligent and effective interlocking for train protection

Smartlock range at a glance

  • No intermediate relays
  • Lower and easier maintenance
  • ERTMS and CBTC ready

With railway systems becoming ever more complex, railway operators and maintainers need an interlocking system that they can count on to guarantee the performance and availability of the system. The Smartlock interlocking family offer flexible, user-friendly and cost-effective solutions, helping Alstom’s customers meet their objectives.

Direct interfacing

The principal and innovative feature of the latest solution in the range, Smartlock 400, is its direct interfacing with trackside objects such as point machines and signals. This removes the need for intermediate relays, meaning that less ground infrastructure (20%) and cabling is required, generating a lower footprint and consequently saving on maintenance costs. 

Flexibility and ease of implementation

While each installation is tailored to the customer’s specific needs, Smartlock’s modular architecture, with standardised interfaces and standard maintenance and configuration tools, guarantees easy application to a host of different railway systems, whether new or existing, from low density regional lines to high speed mainline corridors, or to adapt to a future variation in network traffic. It can interface with existing trackside objects without modification, and it is compatible with three different application languages. With this adaptability, project implementation times are much lower than other options available on the market.

Seamless integration with ERTMS and CBTC systems

Thanks to its network-based architecture, Smartlock makes for simplified interfaces with advanced train supervision and train control systems such as mainline ERTMS and urban CBTC, in addition to efficient maintenance systems that map out the status of objects along the line. When an anomaly occurs, an alert is sent to the nearest maintenance staff member indicating the part affected and the action required. All of this ensures faster troubleshooting and enhanced availability.
