Type approval tests on a 'Portec' insulated rail joint: joint B (RR-STR-94-083)

High axle loads, combined with rails of modest height, create a severe environment for insulated joints on BR. To reduce the risk of premature joint failure in service, a "Type Approval" endurance test has been developed. This test simulates the type of loading environment (ie. the bending moment, shear forces...
