Grand Paris Express is arguably the largest transport project in Europe.

It consists in a fundamental rethink, redesign and focus on the public transport network on the scale of the metropolitan area. The purpose of this exercise is to avail Grand Paris with multimodal transport solutions, more integrated transport services, hence supporting a model of polycentric development.

Grand Paris Express in figures

  • 4 additional lines
  • 200 km of new railway lines
  • 68 brand new interconnected stations
  • 2 million passengers every day
  • a train every 2 to 3 minutes
  • a 100% automatic metro system
  • 90% of lines will be built underground

Grand Paris Express' routes

Grand Paris Express, as an automated transit network, is the new metro of the Capital Region. With its 68 new stations and 200 kilometers of additional tracks, Grand Paris Express consists of a ring route around Paris (line 15) and lines connecting developing neighborhoods (lines 16, 17 and 18). Additionally, Grand Paris Express also involves the extension of existing metro lines. Its 4 new lines circle the capital and provide connections with Paris’ 3 airports, business districts and research clusters. It will service 165,000 companies and daily transport 2 million commuters.


Grand Paris Express will mark a break with the way the Paris transport network operates, creating new patterns of mobility by facilitating travel between the suburbs. In enabling regional areas to engage in dialogue both with each other and with Paris, Grand Paris Express will provide businesses with a wealth of opportunities fostering economic development.

Grand Paris Express will significantly cut down travel time:


- It will take only 34 mins - instead of 53! - for a company director to get from Roissy Charles-de-Gaulle Airport to La Défense
- It will take only 15 mins - instead of 1 hour and 6 mins! - for a researcher to get from Orly Airport to the Paris Saclay University Campus

New train stations

As a pillar of this project, the function of stations has been reviewed from the ground up, creating places and spaces where people will do more than just walk through to get on their train. It is intended that this new model will give local stations new functions acting as places to commute, shop, live and work. In summary, the new generation of stations will be welcoming, recognizable from an architectural standpoint, accessible, safe, intermodal, digital, lively... and of course practical!

Saint-Denis Pleyel station (architect: Kengo Kuma) will have more than 250,000 passengers per day

The new metro is on tracks!

Construction work began mid-June 2016 and is due to last until 2030. Grand Paris Express is now in full swing. In their local neighbourhoods, people living in the inner or outer rings around Paris, Franciliens, and Parisians have seen the mushrooming of workers’ cabins, worksites, trucks ferrying earth, drilling operations...

    In a nutshell, the project is about:


    - developping rapid transit lines across the whole of the metropolitan area                                                      

    - redesigning the living space promoting mixed use of this space

    - curbing urban sprawl promoting the use of public transport            

    The ongoing Grand Paris Express project will have a positive impact on urban planning, housing, businesses and environmental protection. It offers a unique opportunity for all stakeholders including developers, transport operators, public and private investors, construction companies, architects, urban planners and the population of the Grand Paris as a whole.
