By 2014 a 48 km railroad between the mountain and the coastal cluster will begin operating, running parallel to the highway. Running at a capacity of 8,500 passengers per hour, it will reduce the trip time between the two clusters to less than half an hour.
Another 2.7 km-long railway line will connect Sochi Airport and Adler. Although it will be quite short, the capacity of this railway section will be very high; in a 24-hour period, up to 64,000 people will be able to travel in just one direction alone.
Other railway networks in the region will also be upgraded, which will significantly increase passenger flow. For example, the section of the coastal railway between Sochi and Tuapse will become double-track.
