This report is one of a series of reports associated with the Cold Weather Transit Technology (CWTT) program of the Urban Mass Transportation Administration. The CWTT program is a project to improve transit operations in severe ice, snow, and cold environments. This report presents theoretical and experimental results regarding the laser melting of ice from transit rails. The objective of this study is to present estimates of the energy requirements to either melt ice from transit rails or establish a thin melt zone at the ice-transit rail interface. The process radiates electromagnetic energy at laser wavelengths to and through an ice layer on a metal substrate and which is absorbed by both the ice and substrate. The results are used to estimate the equipment requirements necessary for implementation of laser deicing techniques.
