    en.wikipedia.org/wiki/Guard_rail_(rail_transport)

    Guard rails at Diêu Trì railway station, Vietnam This curved track in Myanmar, near Pekon, includes a guard rail on the inside rail of the curve. In rail transport, guard rails or check rails are rails used in the construction of the track, placed parallel to regular running rail to keep the wheels of rolling stock in alignment to prevent derailment.

  3. Track gauge - Wikipedia

    en.wikipedia.org/wiki/Track_gauge

    The most common use of the term "track gauge" refers to the transverse distance between the inside surfaces of the two load-bearing rails of a railway track, usually measured at 12.7 millimetres (0.50 inches) to 15.9 millimetres (0.63 inches) below the top of the rail head in order to clear worn corners and allow for rail heads having sloping ...

    en.wikipedia.org/wiki/Railway_track

    A railway track (CwthE and UIC terminology) or railroad track (NAmE), also known as permanent way (CwthE) [1] or "P Way" (BrE [2] and Indian English), is the structure on a railway or railroad consisting of the rails, fasteners, sleepers (railroad ties in American English) and ballast (or slab track), plus the underlying subgrade.

  5. Minimum railway curve radius - Wikipedia

    en.wikipedia.org/wiki/Minimum_railway_curve_radius

    The minimum railway curve radius is the shortest allowable design radius for the centerline of railway tracks under a particular set of conditions. It has an important bearing on construction costs and operating costs and, in combination with superelevation (difference in elevation of the two rails) in the case of train tracks , determines the ...

    en.wikipedia.org/wiki/Track_geometry_car

    Alignment – "Alignment is the projection of the track geometry of each rail or the track center line onto the horizontal plane," (FRA Definition). [8] Also known as the "straightness" of the tracks. Crosslevel – The variation in cant of the track over the length of a predetermined "chord" length (generally sixty-two feet). On straight or ...

  8. Rail inspection - Wikipedia

    en.wikipedia.org/wiki/Rail_inspection

    The first rail inspection cars were created by Dr. Sperry. Since then, many new models have rolled out. These rail inspection cars are basically their own train with inspection equipment on board. The probes and transducers are mounted on carriages located underneath the inspection car. Modern-day inspection cars now use multiple NDT methods.

  9. Track gauge conversion - Wikipedia

    en.wikipedia.org/wiki/Track_gauge_conversion

    Track gauge conversion is the changing of one railway track gauge (the distance between the running rails) to another. In general, requirements depend on whether the conversion is from a wider gauge to a narrower gauge or vice versa, on how the rail vehicles can be modified to accommodate a track gauge conversion, and on whether the gauge conversion is manual or automated.
