The most popular among citizens and tourists kind of transport in Moscow is the Moscow Underground (The Metro). There are more than 200 Metro stations today and this number is constantly growing, which enables you to move effortlessly between any locations on the map. The navigation throughout the Metro is much easier in comparison with underground services in other cities. The thing is, the metro map is almost symmetrical and reminds of a spider's net. There are nine lines situated as divergent rays pointing in all directions and intersecting near the center. Also, there is a circle line which intersects with all other lines. For easier navigation, all the stations in Moscow Metro are being announced in English.
Also, Metro isn't valued solely for its practical usage. It is the part of our cultural heritage, and every visit to the halls of Metro is like a visit to a museum of architecture.
The Metro's working hours are from 5.30 a.m. to 1 a.m (with rare exceptions such as the New Year's). The one-way adult ticket costs 55rubles (little less than a dollar), but you can save more than 30% of its cost by using the Troika card.
The Troika card is a contactless reusable card designed to pay for public transport in Moscow. You can top it in metro ticket offices, ticket vending machines or even online. Troika can be used in Metro, buses, trams, and trolley-buses. The one ride costs 35 rubles, and there are also discounts for doing more than one ride in less than 90 minutes.
The newest addition to the spider's net of Metro is the Moscow Central Circle (MCK) which makes another circle line a bit further away from the city center than a Metro circle line. It is not the part of Metro per se because it's not underground, but it's almost fully integrated into the Metro infrastructure.
