Nearly the entire line runs through the downtown core of Barcelona, Spain's second-largest city and one of the most densely populated cities in Europe.
The project involves the design, construction, financing, operation and maintenance as well as the provision of the rolling stock. Payments are based on an availability mechanism until it is turned back over in 2032.
