There are flights from Pyongyang, Hamhung and Chongjin, although foreigners are not allowed to use these. The extensive rail network built by the Japanese during the World War II has been broken by the separation of North and South Korea, but the main passenger routes run from Pyongyang to Sinuiju, Haeju and Chongjin. Service, however, is slow.
Traffic drives on the right.
There are no buses between cities. There are very few road signs. Pyongyang has a 2-line metro and regular bus services.
