Ticket prices
The trip cost depends on travel distance; transfers to and from the Moscow Metro and the MCC are free.[13]
At MCD-1 and MCD-2 there are three tariff zones:
- "Central" (within the boundaries of the stations Mark – Setun, Volokolamskaya – Ostafyevo). The cost for the Troika card is 40 rubles. You can also use a ticket for 60 trips, tickets for the number of days recorded on the Troika, and a credit card. All prices are the same as in Moscow Metro.
- "Suburb" (for trips through the territory of the Moscow region and to Moscow within the MCD). A one-time trip at the "Wallet" tariff costs 45 rubles, a ticket for 90 minutes costs 83 rubles.
- "Far" (for trips from stations outside the MCD). The price is made up of 23 rubles for each zone of suburban trains to the borders of the MCD and 45 rubles of the MCD "Wallet" tariff or 83 rubles at the 90-minute tariff.
