As an integrated organisation, RATP Group oversees large-scale public transport projects, armed with its industry expertise and the collective commitment of its teams. The Group deploys its interconnected skills across various modes, ground conditions, and contexts, by mobilising its globally unique expertise. “To successfully execute major public transport projects, being an integrated organisation is not merely an asset, but an imperative! This approach enables the Group to share its experience in maintenance, operations, and engineering, to provide safer and more efficient service.” Sylvie Buglioni Director, Technical and Industrial Projects Division, and Member of the RATP Group Executive Commitee In carrying out such complex projects, RATP Group has overcome numerous challenges: Ensuring service continuity during ongoing works, by keeping traffic disruptions to a minimum, to provide passengers with the same level of service; Adapting to various ground conditions, by leveraging the Group’s highly specialised expertise in civil engineering, geotechnics and public transport systems; Complying with schedules and budgets; Guaranteeing the safety of passengers, employees and service providers. Carrying out grand-scale public transport projects: strength through integration Projects of exceptional scale involve a wide array of expertise, which only an integrated group can deftly coordinate. This is how transport authorities and regional councils can be reassured that sustainably efficient networks will be built within budget and schedule. Our comprehensive knowledge of project life cycles, equipment and infrastructure, as well as operational agility across transport modes, and our project-oriented culture are the fundamental qualities that have enabled the Group to rise up to major challenges, An integrated and expert approach In its multiple roles as designer, project owner, project manager, transport operator, and maintenance operator, RATP Group boasts the full range of skills and expertise required in running public transport systems. The Group is also one of the rare few operators with multi-modal experience, ranging from RER suburban lines to metros, trams and buses. Such broad expertise has proven invaluable in meeting the specific challenges of complex projects. “Our specific expertise in mass transit allows us to reconcile the needs expressed by customers, the infrastructure manager, maintenance operator and transport operator. As one of our qualities, it enables us to chart ambitious, yet realistic road maps for the projects that we lead.” Claire-Hélène Coux Deputy Director, Project Management Division Unprecedented extension of the Île-de-France regional network Since 2012, the Île-de-France regional network has undergone an unprecedented expansion, in which RATP Group played a major role. This is notably the case with the recent extensions to metro lines 4, 11, 12, and 14, and tram line extensions and constructions. Our projects Metro line 14: doubling the length of a fully automated line With over 14 additional kilometres served, eight stations, and a new maintenance centre and depot, not only did the metro line 14 extension defy all norms, it was also completed in record time. Metro line 14 will thus become the backbone of the future Grand Paris Express network. Metro line 4: extending and automating a long-standing line Metro line 4 stretches northwards and southwards to serve major SNCF train stations, and strategic hubs, while carrying 700,000 passengers daily. Alongside the line’s extension in 2022, automation works were launched in 2016. The transformation was completed as planned in January 2024. Tram line T3b: extending the busiest tram line in the Île-de-France region Completed in five years, the extension of tram line T3b up to Porte Dauphine was commissioned in April 2024, covering a distance of 3.2 kilometres across seven new stations. Maintaining and upgrading existing assets, a unique set of skills Be it the construction of new lines, or the upkeep of existing lines, the Group adopts its distinctive approach. Through its vision as an integrated organisation, RATP Group is able to develop the sustainable solutions to retrofit maintenance centres and information systems, and successfully convert the way the Île-de-France regional bus network is powered. The Group transforms its industrial assets, thereby providing added technological, operational, and environmental value. The company has also demonstrated its ability to develop programmes in its various areas of expertise, such as rolling stock, systems, and infrastructure, with the goal of improving network efficiency. Restructuring industrial equipment Large-scale projects present an opportunity to restructure industrial equipment. New maintenance centres are built already equipped with cutting-edge technology, boasting ergonomic workstations to ease employees’ working conditions. This is notably the case at the maintenance centres in Sucy-en-Brie (RER line A), in Saint-Ouen and Morangis (metro line 14), and in Rosny-sous-Bois (metro line 11). Bus2025: a wide-scale energy transition operation The Bus2025 programme is the first energy transition project of its kind in Europe. Through the programme, RATP, in conjunction with Île-de-France Mobilités, will fully convert 25 bus depots to electricity and biomethane, replacing the majority of the bus fleet while guaranteeing the continuity of passenger service. The project, which was launched ten years ago at the COP21 conference, will contribute to the reduction of greenhouse gas emissions. “The Bus2025 programme actually relies on RATP’s three areas of in-house expertise: engineering, operations, and maintenance. Coordinating them was a feat in itself! Simultaneously, infrastructure had to be modified so that vehicles could be charged with either electricity or biomethane, the new rolling stock acquired by Île-de-France Mobilités had to be deployed, and the new combined system had to be used in a production environment.” François Warnier de Wailly Director, Bus2025 programme A programme to optimise the life cycle of rolling stock To limit the impact that rolling stock has on the environment, RATP Group upgrades and refurbishes older vehicles to optimise their life cycles. With the arrival of the new next-generation trains that are now deployed on metro line 14, the Group has seized the opportunity to repurpose the line’s former rolling stock by running it on metro line 1. In turn, automated trains that used to service metro line 1 have been removed from circulation to operate on metro line 4, which was undergoing automation at the time. Trains with a driver’s cabin, which had been running on metro line 4 until then, were subsequently reassigned to metro line 6. Key figures 18 out of 25 bus depots already converted to electricity or biomethane by July 2024 19 stations renovated and upgraded on tram line T1 Over 1,000 platform screen doors installed at the 29 metro-line-4 stations Engaging with our stakeholders In the Île-de-France region, in France and worldwide, the Group contributes its know-how across project types, by partnering with the best external experts. The Group also provides insight and experience in operations and maintenance to offer cutting-edge rolling stock technology alongside its industrial partners. As a trusted regional name, RATP Group works with these partners on projects that leave minimal impact on passengers’ and residents’ daily routines and environment, by providing solutions that enhance the quality and durability of projects. Keeping regional ambitions alive “Our city is lucky to now have two metro stations, following the extension to metro line 11. These stations have considerably improved the public transport service in the municipality, and are easing our inclusion as part of the city.” Lionel Benharous Mayor of Les Lilas In Casablanca, Morocco, 25 additional kilometres and 40 new stations now put essential services within reach of residents throughout the city.The city of Belgrade, Serbia, has relied on the Group’s expertise to commission three metro lines, stretching over a distance of 69 kilometres. RATP Dev teams have been supporting the city in its strategic choices involving the operation and maintenance of such an automated system.In Angers, France, RATP Dev has commissioned two new tram lines, which it manages. Rising to challenges of the future The Group has long been committed to an ambitious approach to corporate social and environmental responsibility, in which its major projects are seen as opportunities for change, to create more sustainable cities.In the future, networks that have to be operated and maintained will become far more extensive, and more vulnerable to the higher environmental risks. To counter these issues, the Group is increasing its ability to take on major projects by factoring in environmental considerations at every level. This is the case with the large-scale drive to plant greenery in the Group’s properties, which not only introduces nature back into the city, but chooses plant species that consume less water, such as the grass on tram line T3b platforms.
