www.bdz.bg is the official website to buy your train tickets in Bulgaria.
Trains in Bulgaria are primarily operated by BDZ (Bulgarian State Railways), which provides an extensive network of domestic and international services. The rail system connects major cities like Sofia, Plovdiv, Varna, and Burgas, as well as scenic routes through the countryside and the Balkans. BDZ offers both intercity and regional trains, with options for sleeping cars on longer routes, making it a convenient choice for both day and overnight travel.
While Bulgarian trains are generally affordable, the quality of service can vary, with some older trains still in use, but recent efforts have been made to modernize certain parts of the network. For international travel, BDZ connects to neighboring countries like Greece, Turkey, and Romania.
