  2. Railroad switch - Wikipedia

    en.wikipedia.org/wiki/Railroad_switch

    On European high-speed lines, it is not uncommon to find switches where a speed of 200 km/h (124 mph) or more is allowed on the diverging branch. Switches were passed over at a speed of 560 km/h (348 mph) (straight) during the French world speed run of April 2007. [9]

    A contract was let in 1972 to begin grading the route for the Railroad Test Track (RTT), a planned 14 mi (23 km) high-speed loop operating conventional rail vehicles up to 160 mph (260 km/h); within the high-speed loop, a Dynamics Track sub-loop 9.9 mi (15.9 km) long would investigate passenger and freight train dynamics at slower speeds.

  4. High-speed rail - Wikipedia

    en.wikipedia.org/wiki/High-speed_rail

    High-speed rail (HSR) is a type of rail transport network utilising trains that run significantly faster than those of traditional rail, using an integrated system of specialised rolling stock and dedicated tracks. While there is no single definition or standard that applies worldwide, lines built to handle speeds of at least 250 km/h (155 mph ...

  5. High-Speed Ground Transportation Act of 1965 - Wikipedia

    en.wikipedia.org/wiki/High-Speed_Ground...

    The High-Speed Ground Transportation Act of 1965 (Public Law 89-220, 79 Stat. 893) was the first attempt by the U.S. Congress to foster the growth of high-speed rail in the U.S. The High Speed Ground Transportation Act was introduced immediately following the creation of Japan's first high-speed Shinkansen, or "bullet train" and was signed into ...

  6. Overhead line - Wikipedia

    en.wikipedia.org/wiki/Overhead_line

    All systems with multiple overhead lines have a high risk of short circuits at switches and therefore tend to be impractical in use, especially when high voltages are used or when trains run through the points at high speed. The Sihltal Zürich Uetliberg Bahn had two lines with different electrification.

  7. Hyperloop - Wikipedia

    en.wikipedia.org/wiki/Hyperloop

    Concept art of hyperloop inner workings. Hyperloop is a proposed high-speed transportation system for both passengers and freight. [1] The concept was published by entrepreneur Elon Musk in a 2013 white paper, where the hyperloop was described as a transportation system using capsules supported by an air-bearing surface within a low-pressure tube.

  8. Krytron - Wikipedia

    en.wikipedia.org/wiki/Krytron

    The krytron is a cold-cathode gas-filled tube intended for use as a very high-speed switch, somewhat similar to the thyratron. It consists of a sealed glass tube with four electrodes. A small triggering pulse on the grid electrode switches the tube on, allowing a large current to flow between the cathode and anode electrodes.

  9. Hanover–Würzburg high-speed railway - Wikipedia

    en.wikipedia.org/wiki/Hanover–Würzburg_high...

    The Hanover–Würzburg high-speed railway is a double-track, electrified high-speed railway between Hanover and Würzburg in Germany, 327 kilometres (203 mi) in length. The line, built between 1973 and 1991, was the longest contiguous new project constructed by Deutsche Bundesbahn .
