1) Calculated values conforming to DIN 636, Part 2
2) Calculated values (based on C, C₀)

Determination of the dynamic load capacities and moments is based on a travel life of 100,000 m.
Often only 50,000 m are actually stipulated. For comparison: Multiply values C, M_t and M_L from the table by 1.26.
