Reduced impact bonded insulated joint designs

摘要

TTCI looks to extend bonded insulated joints' service life and make heavy-axle-load service more efficient. Bonded insulated joints (IJ) have been highlighted as impediments to efficient heavy-axle-load (HAL) bulk commodity service. As other track components have improved during the past 10-20 years, bonded IJ performance has remained the same or worsened under increasing HAL traffic. Recent surveys of IJ life in HAL service show average lives of 170-200 mgt.
