Conventional signalling at a glance

  • A complete product portfolio, providing vital control for urban applications (traffic control, speed control, train detection)
  • Supporting a low-impact approach to transit service
  • Designed for efficient maintainability

Alstom offers an extensive range of solutions for customers wishing to modernise their passenger services and enforce safe train operations.

Modular and adaptable

Alstom’s range of vital signalling solutions has been designed to meet the crucial requirements of safety, reliability and functionality. Its modular approach means that clients can choose either full train control systems or gradual implementation from basic train control. Solutions can be configured with a centralized traffic supervision system to minimize traffic disturbance and pursue schedule and headway performance, and the on-board subsystem makes it possible to guarantee safe train movements, supervising train speed to attain the required performance level.
