Finished emergency station

One important element of the tunnel project is the construction of two emergency stations designed to quickly and safely offload passengers from a burning train. Though the stations are 20 kilometers apart, the idea is that if a troubled train can make it to the station, passengers can quickly disembark and escape through special tubes that take them to adjacent safety tunnels. Those tunnels, because of a slight overpressure, are supposed to be free of smoke, no matter how much is coming from a burning train.
