TESTING OF INTEGRAL COACH STRUCTURE

Following the successful design and construction of Inter-City diesel multiple-unit trains in 1957, the Swidon Works designed an integral coach to comply with the B.R. specification for coaches operating on main lines. The combined coach body and underframe structure was required to be capable of carrying all vertical loads and resist an end crushing load of 200 tons without permanent deformation. Testing of the prototype was in general accordance with conditions adopted by the U.I.C. Office of Research and Experiments, Committee B.7. The tests covered static vertical load and compression at end coupled attachments. Results showed satisfactory performance of the shell under vertical load. Window pillars adequately carried their share of the resistance. Compression load tests showed an upward longitudinal deflection of 7 mm and a shortening of the coach body of 10 mm. The tests confirmed that the general design of body shell met the requirements of British Railways Specification for main line coaches and also normally resists the conditions laid down by Committee B.7 in so far as they apply to coaches with control couplers.
