Riyadh, the capitale city of Saudi Arabia is the largest city in the Arabian Peninsula. With more than five million inhabitants, this large city had no public transport network in 2010..

Line B of the Rennes metro a future line that will cross the city from west to east for 14km and will serve 15 stations. This second line will be inaugurated in the second half of 2020. It will be the first line in the world to use Neoval technology, an evolution of light automatic vehicletechnology used for the first line.

The Lusaïl project is certainly one of the most atypical: to build a transport network on a city that exists for the moment only on paper!

Due to its urban location and the heavy traffic, this 1 757 meter long tunnel has specific requirements. The dense traffic (47 000 vehicles per day) puts the ventilation elements under heavy pressure and wear.

Cairo is the most densely populated city in Africa and in the Arabian world and its transport needs are considerable. It was estimated that its public transport system can handle up to 4.9 million journeys per day while a study led in 1990 showed that to support its entire population needs, Cairo would need to be able to handle 8 million journeys per day. To deal with this issue, the Cairo subway opened a third line whose first part was inaugurated in February 2012. It has 3.4 km of underground for a total line of 35.2 km which should be achieved by 2017.

In 2009 Paris City Hall launched a series of renovation on its 22 urban tunnels. Among them, the Neuilly tunnel, 440 m long, in the center of Paris.

The Maurice Lemaire tunnel is one of the longest tunnels in France (6 950 m). It is located between Saint-Marie-aux-Mines(68) and Lusse (88) and has been subject to a vast program of upgrades. A safety gallery was dug in order to renovate the ventilation system.

F2A along with the client EMA and the building company Colas Rail, have been involved in the extension of line 1 of alger’s subway untill the Bachdjara 1 and 2, El Harrach Gare and Centre stations
