A study by the Transportation Technology Center, Inc. (TTCI) on railroad switches found that switch maintenance, rather than an improved switch design, is the key to both maximum product service life and reduced derailments occurring from broken, worn or damaged switches. The study involved a literature review, a railroad performance expert survey, and a switch failure mode analysis of North American freight railroad mainline and yard switches. Results from the study lead to the identification of the most common railroad switch designs used, the significant switch failure modes that were found, and potential research opportunities.
