32 6.1 Conclusions The results of this synthesis indicate that the occurrence of rail defects, broken rails, and broken rail derailments on transit systems is consistent with the rate of development found in other studies of U.S. railroads that look at larger populations of defects.

Conclusions and Suggestions for Further Research 33 Track inspectors or track circuits are primarily responsible for finding these types of broken rails, which raises a concern; reliance on track circuits to find broken rails is not a practical means for managing risk. In addition, as transits (and railroads)

34 Maintenance Planning for Rail Asset Management -- Current Practices could also help transit systems identify the potential benefits of risk-based scheduling -- particularly the smaller systems that do not currently detect significant numbers of internal rail defects. Because this type of research for some transit agencies would require improved record keeping, the introduction of rail defect and maintenance data systems would be of real value.
