The World Bank estimates that the railway network in Romania comprised 22,298 kilometres (13,855 mi) of track in 2004, which would make it the fourth largest railroad network in Europe. The railway transport experienced a dramatic fall in freight and passenger volumes from the peak volumes recorded in 1989 mainly due to the decline in GDP and competition from road transport. In 2004, the railways carried 8.64 billion passenger-km in 99 million passenger journeys, and 73 million metric tonnes, or 17 billion ton-km of freight.
