INSULATED RAIL JOINT DEVELOPMENT AND RESEARCH. SECOND PROGRESS REPORT

A second progress report on insulated rail joint development and research is presented. Objectives of the work and principles of the problem are discussed, and laboratory tests citing the experience of eight service test joints are reviewed. Characteristics of a rail joint are enumerated, and reasons for development of better insulated joints are presented. It is noted that the AAR design includes joint bar, insulation, armor and thimbles all molded and bonded into an integral unit, and the design has other advantages also. Exposure of the joint to a rolling load machine is also discussed.
