UIC Classification of Locomotive Axle Arrangements

The UIC classification of locomotive axle arrangements describes the wheel arrangement of locomotives, multiple units and trams. It is set out in the International Union of Railways (UIC) "Leaflet 650 – Standard designation of axle arrangement on locomotives and multiple-unit sets". It is used in much of the world. The United Kingdom used a related scheme. The United States uses the simplified AAR wheel arrangement for modern locomotives.

It is a more versatile system than Whyte notation, making fewer assumptions about locomotive layout. Some locomotives are impossible to classify using Whyte notation, but UIC classification handles them easily. The UIC classification is also much more suited to diesel and electric locomotives.

Famous quotes containing the words locomotive, axle and/or arrangements:

    The American people have done much for the locomotive, and the locomotive has done much for them.
    James A. Garfield (1831–1881)

    The Star that bids the Shepherd fold,
    Now the top of Heav’n doth hold,
    And the gilded Car of Day,
    His glowing Axle doth allay
    In the steep Atlantick stream,
    John Milton (1608–1674)

    Autonomy means women defining themselves and the values by which they will live, and beginning to think of institutional arrangements which will order their environment in line with their needs.... Autonomy means moving out from a world in which one is born to marginality, to a past without meaning, and a future determined by others—into a world in which one acts and chooses, aware of a meaningful past and free to shape one’s future.
    Gerda Lerner (b. 1920)
