I took this picture about 2 weeks ago when I was in chisinau. I took the Bacau-Chisinau overnight train. Some of these trains are part of a very long route. Mine was from Bucharest to Moscow. Few days later I continued my journey to Kiev. I went to Chisinau train station the day of and while the cashier spoke limited english she wrote down the times of departure and respective costs of 1st, 2nd, 3rd class. I just pointed my finger at which departure time and which class and that was that. You can pay with credit card no problem.
