Train Event Recorder - Development

Development

The earliest event recorders were the mechanical "TEL" speed recorders of 1891, which recorded both time and speed. The TEL's manufacturer, Hasler Rail of Switzerland, remains a leading producer of train event recorders.

France developed the Flaman Speed Indicator and Recorder. In Germany, the Indusi train protection system had included recording equipment from early on using a ticker tape on paper. For I60R a generalized recorder system was installed (Datenspeicherkassette / data storage cassette) that allowed to enter the train number, driver info, train weight along with the driving events. The standardized DSK black box allows for approximately 30,000 km of general recording data and 90 km of detailed recording data. Later models of the DSK are electronic especially since the introduction of the computerized PZ80/PZB90 train protection generations. Modern Train Event Recorders follow International or National Standards like IEEE Std. 1482.1-1999, FRA 49 CFR Part 229, IEC 62625-1 etc. specifying the digital and analogue data to be acquired, recorded and transmitted for further analysis. The need for event recorders to sustain an accident has led to companies like Hasler Rail (Switzerland), Bach-Simpson (USA), Far Systems (Italy), MIOS Elettronica (Italy) to develop crash protected memory modules as a part of their event recorders. These new generation event recorders have growing demand both for rapid transit systems and mainline trains, in Europe, United States,India, etc.

Famous quotes containing the word development:

    I have an intense personal interest in making the use of American capital in the development of China an instrument for the promotion of the welfare of China, and an increase in her material prosperity without entanglements or creating embarrassment affecting the growth of her independent political power, and the preservation of her territorial integrity.
    William Howard Taft (1857–1930)

    The highest form of development is to govern one’s self.
    Zerelda G. Wallace (1817–1901)

    If you complain of people being shot down in the streets, of the absence of communication or social responsibility, of the rise of everyday violence which people have become accustomed to, and the dehumanization of feelings, then the ultimate development on an organized social level is the concentration camp.... The concentration camp is the final expression of human separateness and its ultimate consequence. It is organized abandonment.
    Arthur Miller (b. 1915)
