A 57-km long tunnel has been built through the Great Alps, in Switzerland. It will take a train travelling at 200 km per hour, some 20 minutes to pass through the tunnel. It will become operational by December 11. It took 2,405 workers, 20 years to complete construction of this tunnel, at a cost of Rs. 67,000 crores. The journey time through Europe will also decrease largely because of the tunnel.
