The Chui valley in the north and the Ferghana valley in the south were endpoints of the Soviet Union's rail system in Central Asia. Following the emergence of independent post-Soviet states, the rail lines which were built without regard for administrative boundaries have been cut by borders, and traffic is therefore severely curtailed. The small bits of rail lines within Kyrgyzstan, about 370 km (1,520 mm broad gauge) in total, have little economic value in the absence of the former bulk traffic over long distances to and from such centers as Tashkent, Almaty and the cities of Russia.
There are vague plans about extending rail lines from Balykchy in the north and/or from Osh in the south into the People's Republic of China, but the cost of construction would be enormous.
