British Rail Class 43 (HST)

The British Rail Class 43 (HST) is the TOPS classification used for the InterCity 125 High Speed Train power cars, built by BREL from 1975 to 1982.

The class is the fastest diesel locomotive in the world, with an absolute maximum speed of 148 mph (238 km/h), and a regular service speed of 125 mph (201 km/h). There are claims that this diesel rail speed record has been broken twice unofficially: by the TEP80 Russian train in 1993 achieving 271 km/h (168 mph), and the Talgo XXI Spanish train reporting 158 mph (254 km/h) in 2002.

Famous quotes containing the words british, rail and/or class:

    Anthropology is the science which tells us that people are the same the whole world over—except when they are different.
    Nancy Banks-Smith, British columnist. Quoted in Guardian (London, July 21, 1988)

    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)

    All this class of pleasures inspires me with the same nausea as I feel at the sight of rich plum-cake or sweetmeats; I prefer the driest bread of common life.
    Sydney Smith (1771–1845)
