Network

The current rail network is based on the inheritance from the former Soviet Union and as such has a broad gauge of 1,520 mm (4 ft 11 5⁄6 in). While this provides a smooth transit at international borders to countries of the former Soviet Union, the railway in China has the standard gauge of 1,435 mm (4 ft 8 1⁄2 in); thus there is a break-of-gauge at the eastern borders at Dostyk and at Korgas.

KTZ controls about 15,000 km (9,300 mi) track (2005) which is being expanded. The Kazakhstan sections of the old Trans-Aral Railway, the Trans-Caspian railway, and the Turkestan-Siberia Railway have become incorporated into the KTZ. 3000 km are electrified at 25 kV 50 Hz AC.

Famous quotes containing the word network:

    Of what use, however, is a general certainty that an insect will not walk with his head hindmost, when what you need to know is the play of inward stimulus that sends him hither and thither in a network of possible paths?
    George Eliot [Mary Ann (or Marian)

    A culture may be conceived as a network of beliefs and purposes in which any string in the net pulls and is pulled by the others, thus perpetually changing the configuration of the whole. If the cultural element called morals takes on a new shape, we must ask what other strings have pulled it out of line. It cannot be one solitary string, nor even the strings nearby, for the network is three-dimensional at least.
    Jacques Barzun (b. 1907)

    How have I been able to live so long outside Nature without identifying myself with it? Everything lives, moves, everything corresponds; the magnetic rays, emanating either from myself or from others, cross the limitless chain of created things unimpeded; it is a transparent network that covers the world, and its slender threads communicate themselves by degrees to the planets and stars. Captive now upon earth, I commune with the chorus of the stars who share in my joys and sorrows.
    Gérard De Nerval (1808–1855)
