Stadler and Siemens to upgrade Lisbon Metro

A consortium of Stadler and Siemens Mobility have won a 114.5 million contract to upgrade the Lisbon Metro. Stadler will supply 14 three-car metro trains, while Siemens Mobility will install its Communications-Based Train Control (CBTC).

Siemens Mobility will install its CBTC system Trainguard MT on the Blue, Yellow and Green lines, and will upgrade the existing equipment. This will include installing its on-board CBTC technology across 70 trains of the existing fleet, as well as on the 14 new Stadler trains.

The contract includes technical training for operation and maintenance, as well as preventive and corrective maintenance of all equipment for the first three years, and the supply of spares and consumables for preventive maintenance for a further two years. The supply period agreed is 77 months, with provisional acceptance planned for 2027.

Modernising the fleet

Stadler will design the vehicles using a modular methodology to better facilitate maintenance. Its stainless-steel car body ensures the vehicles are lightweight and strong. Three double doors per side and carriage will enable passengers to get on and off quickly and easily.

“We are excited about this contract, and proud to have the chance, in partnership with Siemens Mobility, to support Lisbon Metro in its efforts to modernise the fleet”, states Ansgar Brockmeyer, Executive Vice President Marketing and Sales at Stadler Group. “Stadler has recently won major metro projects in Europe and the US. This latest contract confirms the success of our strategy and positions us as a global reference in providing solutions for sustainable urban mobility”.

Train control

The 14 three-car trains will initially be fitted with CBTC Grade of Automation (GoA) 2 but will have the ability to be upgraded to GoA4, so the service can be fully automated in future. Trains will be powered by third rail at 750 V. The 49.6-metre long and 2.78-metre wide vehicles will have 90 seats arranged longitudinally, two places for wheelchair users, and standing capacity for 450 people (6 per square metre).

Siemens Mobility CBTC signalling technology provides real-time data on vehicle position and speed conditions operating in moving block principle, allowing system operators to safely increase the number of vehicles on a rail line. This results in greater frequency of train arrivals and allows more passengers to be accommodated on the system. The train control system is currently also being used in Singapore, Turkey, Brazil, Spain, and China. Andre Rodenbeck, CEO Rail Infrastructure at Siemens Mobility: “The 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.”
