Third rail systems provide traction power to electrified rail systems in many parts of the world, including the United States, and encounter problems such as failures that need to be investigated and remediated.

The TRB Transit Cooperative Research Program's TCRP Synthesis 150: Third Rail Insulator Failures: Current State of the Practice documents the present practices and lessons learned, challenges, and gaps in information related to the use of third rail insulator systems in the United States. The synthesis delivers information that can assist transit organizations in making informed decisions about their third rail insulator systems and mitigation strategies.
