After one night aboard train Rossyia (linking Moscow to Vladivostok), we stopped some time in Balezino. Enough time to stretch our legs and buy some food for the day to the local sellers on the platform.
We purchased a second class ticket for this Trans-Siberian journey and it was very comfortable! Each compartment had 4 beds that turned into 4 seats during the day. You have access all day to hot water and tea to keep you warn and happy.
