    Crosslevel (or 'cross level') is the measurement of the difference in elevation (height) between the top surface of the two rails at any point of railroad track. The two points (each at the head of each rail) are measured at by the right angles to the reference rail. Since the rail can slightly move up and down, the measurement should be done ...

  8. Track spacing - Wikipedia

    en.wikipedia.org/wiki/Track_spacing

    Measurement of track spacing from the rail head to rail head. By definition, the track spacing is given from centre to centre of a rail track. For an actual construction the distance is measured from the inside of a rail head to the matching one of the other track. As far as both tracks have the same gauge this is the same distance.
