58 years after inaugurating Milan’s first underground railway line, six stations opened their doors last year on 26th November to passengers travelling on the city’s new line, the fifth in chronological order, with two more stations opening on the 4th of July 2023.
Once completed (at the end of 2024, the M4 Line, or Blue Line, will connect the old city centre to the eastern part of the city and to other districts to the west.
The new line will carry a rapid, comfortable light-railway service with the latest safety features: the automatic, driverless trains are equipped with an intelligent traffic-control system to ensure passengers enjoy their journey in complete safety. Once completed, the line will have a capacity of 24,000 passengers every hour in each direction.
The underground rail line has zero emissions and will have a positive impact on road traffic by encouraging the use of public transport, with considerable benefits for both the environment and for those who live and work in Milan.
The M4 Line is being excavated underground along “blind” tunnels using TBM technology, apart from the “open air” excavation work for the stations, service systems and other structures. The construction phase is also heavily focused on environmental sustainability: non-polluting, non-toxic and non-hazardous products are being used to consolidate the soil and to ensure tunnelling operations advanced as scheduled.
Among the exceptionally massive contribution Mapei provided to the project, Mapei UTT specialists have been assisting the waterproofing works with consistent technical service as well as waterproofing membranes and accessories. MAPEPLAN synthetic membranes were used to waterproof the foundations of numerous stations (San Cristoforo, Gelsomini, Segneri,Tolstoj, Washington Bolivar, De Amicis, Vetra, Santa Sofia and San Babila).
The wide range of MAPEPLAN products have been used to install a state-of-the-art Vacuum system, which allows for compartmentalization of the watertight system into small independent sections.
