An Italian train makes its way at the north entrance of the new Gotthard Base Tunnel, the world's longest train tunnel, on the eve of its opening ceremony on May 31, 2016 in Erstfeld.
Swiss rail authorities said repairs to the Gotthard Base Tunnel, the world's deepest traffic tunnel and longest of its kind, will take several months after the extent of the damage from a recent freight service derailment was found to be "significantly greater" than initially estimated.
The operator currently assumes that both tunnel tubes will be available again for all rail traffic "to a limited extent" at the beginning of next year, while the undamaged east tunnel tube should be able to operate from Aug. 23 for freight traffic.
It means that rail passengers traveling between north and southernmost Switzerland will be forced to take a more scenic route over the coming months.
The Gotthard Base Tunnel is a high-speed railway route through the Swiss Alps.
