Alstom consortium picked to deliver Dominican Republic’s first monorail system

August 28, 2023 – Alstom (OTC: ALSMY), a global leader in smart and sustainable mobility, announces that the Consortium SIF (led by Alstom and including Sofratesa) has been selected by Fideicomiso para el Desarrollo del Sistema de Transporte Masivo (FITRAM) of the Dominican Republic to deliver an integrated Innovia monorail system for the city of Santiago de los Caballeros. When completed, the 13-kilometre, 14-station Santiago de los Caballeros monorail system will be the first of its kind in the country and in the Caribbean. The system is dimensioned to carry up to 20,000 passengers per hour per direction (pphpd) and will provide faster and more efficient connections between the city’s northwest and southeast areas.

Alstom’s scope within the contract includes system integration, testing and commissioning of the full system and the supply of Innovia monorail trains as well as Cityflo 650 GOA4 driverless signalling, Hesop reversible power supply, conductor rail, high-speed interchange switch systems and depot equipment. Alstom’s share of the contract is worth approximately €370 million. This project is carried out with financing from the French government.

Alstom will deliver the 13 four-car automated Innovia Monorail 300 trains, which incorporate the design and operational features required for a high-capacity urban transport system. These features include automatic driverless operation, bi-directional operations, and compliance with international safety requirements and standards. Capitalising on Alstom’s strong leadership with over 30 years’ expertise in communications-based train control (CBTC), Alstom’s Cityflo 650 CBTC solution — the first driverless rail control system in the Dominican Republic— will support the highest grade of automation (GoA4), allowing for high reliability, shorter intervals between trains, flexible and safe operations, and reduced maintenance costs. To further increase the energy efficiency of the system, Alstom will install Hesop reversible power stations, which translates into not only building fewer substations along the alignment but also recovering and reinjecting up to 99% braking energy from the trains back into the network.

Stadler and Siemens Mobility Win Contract to Modernize and Upgrade Lisbon Metro

The consortium of Stadler and Siemens Mobility have won a €114.5 million contract to provide the Lisbon Metro with a state of the art signaling system and a new fleet of modern trains. Stadler will supply 14 three-car metro trains, while Siemens Mobility will install its Communications-Based Train Control (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.

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.

The 14 three-car trains will initially be fitted with CBTC GoA2 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 49.6m long and 2.78m wide vehicles will have 90 seats arranged longitudinally, two places for wheelchair users, and

standing capacity for 450 people (6p/m2). The new rolling stock will increase comfort and accessibility for passengers, as well as provide enhanced communications, safety, and video surveillance systems.

Siemens Mobility CBTC signaling 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. This is the most extensively deployed automatic train control system in the world and is currently being used in Singapore, Turkey, Brazil, Spain, and China.
