Information about the works in progress:

Why is this work being done?

This work is part of the Metro network’s modernization project, which foresees the installation of a new Communications-Based Train Control (CBTC) signalling system, to replace the existing one by modern equipment that is better suited to meet the demands of today’s service quality standards.

What’s being improved?

Replacement of the railway signalling equipment between the Carnide and Jardim Zoológico section, in order to implement the CBTC system on the Blue line by the end of 2023.

What are the benefits of this intervention?

The CBTC system is a qualitative improvement in the management, operation and programming of the Metro network that will improve the level of the service provided.

The new system will enable continuous control of train movements, as well as an improvement in the frequency and regularity of the public transport service, ensuring a supply of trains, both in quantity and frequency, that is better suited to customer needs.

Work schedule:
5 February 2023 (Sunday)
