The report was written in response to a standing need for a brief summary overview of the safety and reliability problems, applicable government regulations, and current status of industry developments associated with the operation of Lightweight Vehicles (LWV's) over U.S. railroad signal systems. An effort has been made to treat the subject of track circuit shunting sensitivity in as concise a manner as practicable, consistent with the phenomena associated with rolling-wheel/rail-surface resistance of LWV operation. The text describes the highly variable factors involved within wheel/rail shunting sensitivity, describes the current technological development status, and presents recommendations for technological research. It is believed that this can serve as introductory material for development of a program plan for needed FRA research aimed at economical and viable solutions to provide the level of signal system operational safety required for U.S. LWV passenger operation. An Appendix has been included covering Reference Documents, Industry Developed Instruction Manuals, Contacts of recognized experts within the field, special AAR formulas, and related information.
