According to a press release of Sochi Olympics, a light rail system was originally proposed which will span 36 km, but eventually a Russian-style light metro system has been opted. After Moscow's Butovskaya Line and Saint Petersburg's Nadzemny Express, the Sochi Light Metro will be Russia's third light metro, among 11 Russian rail rapid transit systems altogether.
The estimated construction budget is $758,8 million. The system will consist of three interconnected lines, with a total of 86.4 km of track and 24 stations running in a mixture of underground, mountain tunnels, elevated, and at-grade construction:
The Sochi Light Metro will operate three-car Rusich trains at headways of four minutes. The total number of trains is expected to be 80 (160-240 cars). At approximately 800 passengers per train with cruise speeds of 60-70 km/h, the Sochi Light Metro is projected to accommodate a maximum system-wide capacity of 70,000 passengers per hour.
