CORRIDOR 10 - a sustainable way of integrations
shape and relatively small: the longer longitudinal axis may be 10-12 mm, while the shorter transverse
axis may be 5 - 8 mm. This small patch supports the whole wheel load.

The major occurrence of the surface-initiated RCF rail defects are: "head checkings" (Figure 6),
"squats" (Figure 7), "belgrospis" (Figure 8) as well as shelling (Figure 9).
