Currently, 16 metro stations are being built in the capital. Some of them will appear on historical branches. For example, on the Circle Line, almost in the center of Moscow, the thirteenth station, Dostoevskaya, is being built. There are many difficulties. It is impossible to build it using modern methods and using large equipment. Therefore, when cutting through rock, metro builders use mining and blasting and manual methods, which allows them to build bypass tunnels literally right next to the Circle Line tunnels along which trains with passengers run.
