Tunnel Peerdsbos ('Solar Tunnel') The line features a 'Solar Tunnel' near Antwerp. The above-ground tunnel Peerdsbos is comparable to an avalanche gallery except instead of snow it protects the trains from falling trees and the highway traffic on the E19. It was constructed as an alternative to felling parts of the nearby forest. The 'tunnel' is unique as it is covered with 16,000 solar panels. The line's operator claim this provides 3300 MWh of electricity per year and cuts emissions by 2400 tonnes a year.
