The Big Circle Line, whose length is over 70 kilometers long with 31 stations and three train depots, is one of the biggest underground construction project in the world. Launch of the BCL will improve the transport situation in 34 districts of Moscow with a population of 3.3 million people and considerably reduce the burden on other subway lines.
