UIC 520:2003-12

This Leaflet defines the draw gear systems to be used for wagons, coaches and vans, viz. the standard unified screw coupling, the coupling hook and the elastic draw systems. The use of the standardised screw coupler is compulsory for new stock with effect from 1 July 2003. It is recommended, however, that no further supplies of standard draw hooks or their component parts should be ordered.
