STATIC AND DYNAMIC TESTS ON RAIL FASTENING SYSTEMS

Summary:
The Roads and Railways Research Laboratory of the TU Delft (Delft University of Technology)
conducted a series of laboratory tests on of rail fastening systems on concrete sleepers according to
new European CEN standards. The aim was to determine typical parameter values under static and
dynamic loading. The central part of each test series was a dynamic test with 3·106 load cycles. Before
and after this test a number of static tests was carried out. The results showed a variety of results
depending on the type of fastening used. Wear and cracking of some components were also noted.
With a view to the interest of manufacturers/users this test programme may well have the possibility to
develop into a standard test, whereby the CEN standards should be further optimised. A comparable
test programme could also be developed for fastenings systems on slab track or for embedded rail
constructions.
