This paper presents an analysis of train screw coupling used mainly in Europe as mechanical
connection of wagons in train. An analysis of train breaks apart incidents revealed that less than
30 % of the cases were caused by elements of the screw coupling, with coupling links accounting
for only 5 % of the failures. Therefore, the investigation focused on testing the coupling links,
which are safety elements of the screw coupling. The coupling links underwent various inspections,
including visual inspection, dimensional control, non-destructive testing, examination
of chemical composition, and mechanical tests. Dimensional control found longitudinal plastic
deformations of the links. Chemical examination revealed that the links were made of different
material than recommended, but their mechanical properties generally met the recommended
values. However, variations were observed among different links, likely due to different rates of
deformation during testing and operational ...conditions. Overall, the analysis and inspections
provided insights into the condition and performance of coupling links in the screw coupling
system, highlighting the importance of monitoring and maintaining these elements to ensure safe
and efficient railway operations.
