Deviation z p’ in z-direction of consecutive running table levels on any rail, expressed as an excursion
from the mean vertical position (reference line) and calculated from successive measurements is
longitudinal level (Figure 5) [1].
Longitudinal level of track is defined as follows:
z ' x z ' x

Cross level, h, is defined as the difference in height of adjacent running tables computed from the
angle between the running surface and a horizontal reference plane. It is expressed as the height of
the vertical leg of the right-angled triangle having a hypotenuse, s 1 , that relates to the nominal track
gauge plus the width of the rail head, rounded to the nearest 10 mm (Figure 6) [1].
