With interim acceptance planned for 2027, the period of delivery will last for nearly 77 months.

Siemens Mobility Rail Infrastructure CEO Andre Rodenbeck said: “Siemens Mobility’s CBTC system will increase reliability, availability and efficiency of the service delivered by Lisbon Metro while also complying with the high standards of quality and safety required by the operator.”

For easy maintenance, the 49.6m-long, 2.78m-wide vehicles will be designed by using a modular methodology.

With a stainless-steel car body, they will be designed to be strong and lightweight.

The CBTC GoA2 will be primarily deployed onboard 14 three-car trains with the capacity to undergo future upgrades.

The technology offers real-time data regarding the speed and the position of the train, which will enable the operator to increase service frequency safely.

Last week, Siemens Mobility secured a contract to deploy the GoA2 CBTC signalling system on the extension of Metro Line 1 in Salvador, Brazil.
