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.

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!

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.
