These types of rails are those which are secured within the overall fastening system (not independently fixed to the bearers) on wood, concrete and steel bearers, in ballasted track and on slab track, and which have maximum axle loads and minimum curve radii in divergent track in accordance with Table 1. Table 1 – Fastening category criteria Category Maximum design axle load Minimum curve radius kN m A 130 40 B 180 80 C 260 150 D 260 400 E 350 150 NOTE The maximum axle load for Categories A and B does not apply to maintenance vehicles.
