Static loading diagrams to be taken into consideration for the design of rail carrying structures on lines used by international services

Summary

UIC Leaflet 702 contains rules governing vertical static rail traffic loads (characteristic values) required for the calculation of rail structures on international lines.

Section 1 lists two load models, Load Model 71 and Load Model SW/O which are obligatory for member railway companies.

Section two contains the recommended Load Model 2000, designed to take on board the future trend towards higher axle and metric loads (rail freight network).

Reference is made to the theoretical principles underpinning the load models in order to create a link with rolling stock and its load. The leaflet also specifies how the load models should be taken into account during calculations.

Other information required for the calculation of rail structures in connection with Load Models 71 and SW/O, such as effects (e.g. heavy haul, dynamic effects, centrifugal force, braking, starting, etc.) load combinations and and values should be taken from UIC Leaflet 776 .

Rules governing the permissible axle and metric loads in traffic are set out in UIC Leaflet 700 .
