Monorail road was open in Moscow just a few years back. There is but one line of about 4,5 km long which connect only 6 stations. The line is located in northen part of the city and is used rather for fun. Although monorail is a part of Moscow metro system, special tickets are need to be bought(for the same price as original metro ones, though). Monorail trains consist of 6 cars and run every 10-15 minutes.
