Italferr will be responsible overseeing the execution of the project and providing technical support for the five-year scheme which entails building a new 18km underground section with eight new stations to replace a surface section of the line which links Once in the city centre and Moreno. This will allow trains to operate at 3-minute headways and enable the line to carry more 150 million passengers per year.

"The modernisation of the Sarmiento line in terms of technical complexity and duration of the works - five years from March 2018 until the complete realisation of the work - currently represents the most challenging project for Italferr’s activities abroad,” says Mr Carlo Carganico, Italferr’s managing director and general manager.
