The latest addition to the Moscow Metro system is closer to being finished, with tunneling almost complete.
A 24-kilometer tunnel has been built using a unique drill rig designed by Russian and German engineers. It has set a new speed record for underground drilling going through 600 metres in a month. The Slavanski Boulevard station is being built in the town of Strogino in a plan to make the western suburb a part of the city. It's hoped it will be ready to open in December.
