After 1947, a significant infrastructure undertaking was the construction of the country's rail network as Albania was considered as the only country in Europe not to have standard rail service. By 1987, 677 km of railway were constructed in total linking the main urban and industrial centers for the first time since the end of World War II. Train transport was the main public transportation method until 1990. After the collapse of Communism, the network fell into disregard, operating with second-hand carriages in a constant precarious state.
