Light Rail in North America

Light Rail In North America

Light rail is a commonly used mode of rapid transit in North America. The term light rail was coined in 1972 by the U.S. Urban Mass Transportation Administration (UMTA) to describe new streetcar transformations which were taking place in Europe and the United States. The Germans used the term Stadtbahn, which is the predecessor of the North American light rail, to describe the concept, and many in the UMTA wanted to adopt the direct translation, which is city rail. However, in its reports the UMTA finally adopted the term light rail instead.

Famous quotes containing the words america, north, rail and/or light:

    I am reminded by my journey how exceedingly new this country still is. You have only to travel for a few days into the interior and back parts even of many of the old States, to come to that very America which the Northmen, and Cabot, and Gosnold, and Smith, and Raleigh visited.
    Henry David Thoreau (1817–1862)

    The Moon’s the North Wind’s cooky,
    Vachel Lindsay (1879–1931)

    If goodness were only a theory, it were a pity it should be lost to the world. There are a number of things, the idea of which is a clear gain to the mind. Let people, for instance, rail at friendship, genius, freedom, as long as they will—the very names of these despised qualities are better than anything else that could be substituted for them, and embalm even the most envenomed satire against them.
    William Hazlitt (1778–1830)

    Science is spectral analysis. Art is light synthesis.
    Karl Kraus (1874–1936)
