The European TEN-R (Trans Europe Netwok-Rail) programme also provides for a corridor between Amsterdam (NL) and Genoa (IT), which involves crossing Switzerland.
The aim is to reduce greenhouse gas emissions in the transport sector by 60% by 2050. To facilitate the achievement of this limit, the European Commission has put in place a strategy to promote a modal shift towards more sustainable freight transport (river-sea - rail transport). A number of corridors have therefore been defined to absorb road transport and facilitate the movement of goods across Europe. The corridor, mentioned above, between the Netherlands and Italy is in this context.
The AlpTransit project, operating in Switzerland, will make it possible to guarantee a considerable reduction in journey times between Zurich-San Gotthard-Milan-Genoa.
The new Transalpine Railway (NEAT) with the three base tunnels Loetschberg (in service since 2007), Gotthard (in service since 2016) and Monte Ceneri (opened on 4.4.2020 and whose commercial use will begin in December 2020 with the change of timetable) will make it possible to significantly reduce travel times through Switzerland.
The Monte Ceneri base tunnel with its total of 30 km of tunnels (two parallel single-track tunnels, each 15 km long, connected to each other every 300 m by cross tunnels) is one of the most important underground excavation works just completed.
Systemair with its MRT (Metro Rail/Road Tunnel) Division supplied the fans for ventilation during the excavation phase. Starting from the operating cavern located in the centre of the excavation, the four railway tubes branch off both north and south. The need to supply primary air necessary for the four simultaneous advances led to a particular technical solution that exploits two descents. For ventilation during the excavation with phase 1 and 2, 4 AXC1250 axles, 20 AXC1600 two-stage axles and 4 AXC2000 two-stage axles with motor powers from 22 kW to 250 kW have been supplied (Figure 1).Stainless steel on/off dampers and inverters were also supplied to complete the supply.

Systemair also supplied 4 jetfan AJR1600 90 kW (Figure 2).

More recently, in the railway technology phase (installation of railway equipment and systems),
(Fig.3)
Source Alp Transit Gotthard Ltd. and 4 jetfan AJR1250 55 kW (Figure 3) which allowed fresh air to be brought in during the work carried out inside the tunnels.
Once again Systemair was able to reach and guarantee the high technical requirements of the ventilation equipment and find, together with the customer, a technical system solution that made it possible to speed up excavation times and optimise energy consumption.
