    Transrapid 09 at the Emsland test facility in Lower Saxony, Germany A full trip on the Shanghai Transrapid maglev train Example of low-speed urban maglev system, Linimo. Maglev (derived from magnetic levitation) is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance.

    This article provides a list of operational and under construction (or approved) high-speed rail networks, listed by country or region. While the International Union of Railways defines high-speed rail as public transport by rail at speeds of at least 200 km/h (124 mph) for upgraded tracks and 250 km/h (155 mph) or faster for new tracks, this article lists all the systems and lines that ...

  6. Transrapid - Wikipedia

    en.wikipedia.org/wiki/Transrapid

    The super-speed Transrapid maglev system has no wheels, no axles, no gear transmissions, no steel rails, and no overhead electrical pantographs.The maglev vehicles do not roll on wheels; rather, they hover above the track guideway, using the attractive magnetic force between two linear arrays of electromagnetic coils—one side of the coil on the vehicle, the other side in the track guideway ...

  7. North American railroad signals - Wikipedia

    en.wikipedia.org/.../North_American_railroad_signals

    There are two main types of signaling aspect systems found in North America, speed signaling and weak route signaling. [citation needed] Speed signaling transmits information regarding how fast the train is permitted to be going in the upcoming segment of track; weak route signaling transmits information related to the route a train will be taking through a junction, and it is incumbent upon ...

  9. Automatic Warning System - Wikipedia

    en.wikipedia.org/wiki/Automatic_Warning_System

    A train is driving towards a signal that shows clear (green). The train runs over the AWS magnet (which is two magnets, first a permanent magnet and then an electromagnet). The electromagnet is energized. The AWS receiver detects a magnetic field in the sequence: South, North. The south pole comes from the permanent magnet, and the north pole ...
