I - Transport operations: transport operations guarantees transport continuity, quality, performance and safety. The teams are responsible for regulating the services provided on the metro, bus, RER and tramway networks. They make sure the service is regular, safe and punctual while providing real time information. Changes in technologies and passenger requirements mean the Group must make an ongoing effort to continually develop its competencies.

II - Passenger services: the human relations dimension is a vital component of a high-quality public service. Two thirds of RATP's 45,000 employees come into direct contact with passengers. Information desk staff and those responsible for the transport environments in bus, train and tram stations, bus, metro and RER drivers, ticket inspectors and safety staff... these are the different faces of the Company. These people are the initial ambassadors to our customers for everything relating to operations (driving, regulation, safety, etc.) and customer relations (reception, information, sales, assistance, etc.).

III - Maintenance:

RATP maintains its:

• rolling stock (buses, tramways, metro trains, RER trains);
• equipment (catenary systems, lifts, air-conditioning units, etc.);
• infrastructures (stations, tracks, viaducts, tunnels, etc.).

There are three levels of maintenance:

• preventive maintenance carried out during cyclical maintenance operations;
• curative maintenance carried out following a breakdown or malfunction which disrupts passenger services;
• corrective maintenance carried out during technical modifications.

All of the maintenance teams share the same objective: to strengthen equipment performance and availability in order to guarantee a high level of reliability, comfort and safety to all passengers.

IV. Transport engineering, environments and information: RATP provides its passengers with an ever more innovative and high-performance public service, serving urban sustainability. Its expertise covers all the competencies needed to manage a project, from management services to technical/engineering services. Engineering is involved in the upstream studies, technical studies, execution and monitoring. It plays a key role in the design of transport equipment and systems. The RATP group teams monitor technological developments and carry out Research and Development. They are involved in the Greater Paris project and contribute to the Group's development both in France and internationally.

V. IT and telecoms engineering: the IT and telecommunications professions are central to the RATP group's operations and development. Their scope is very broad, including:

• central information systems (accounts, purchasing, management, human resources);
• passenger service systems (sales, real-time traffic information, etc.);
• specific systems for on-board services, traffic regulation applications, maintenance management, etc.

VI. Civil engineering: RATP group's civil engineering provides a comprehensive service, from management to technical and engineering services in France and abroad. It supports the Group's development as it builds new 21st century transport networks that meet current sustainability challenges. It manages network expansion and modernisation projects and existing passenger environments. It designs engineering works and provides optimised services: infrastructure studies, architecture and town planning assessments, geotechnical studies, etc.

VII. Support functions: the RATP group's performance relies on the teams responsible for cross-disciplinary functions such as finance, legal, human resources, purchasing, marketing and communication. They ensure the coherence of the Company's policy as well as its competitiveness, while offering constant support to teams on the ground.
