Summary

This paper reports on three series of tests which were carried out on full-scale sections of rail that had been treated by laser cladding aiming to create a layer (~1-2mm) of high performance material on the rail head. In the first series of tests wear and rolling contact fatigue experiments were carried out on one metre lengths of clad rail track using The University of Sheffield's full-scale wheel-rail test facility (FSTF). In a second series of tests on the FSTF, one metre long sections of rail were tested including an insulating "end-post" inserted into the head of the rail halfway along the length. This configuration simulated an insulated block joint loaded under dry conditions and with plastic deformation at the insulating end-post measured periodically. The third test series used a four-point bend fatigue configuration to load clad rail specimens to investigate the integrity of the clad/substrate bond.
