ABSTRACT: This report presents results from an evaluation of the economic benefits of concrete- versus wood-tie track. The analysis includes the life-cycle capital, maintenance, and renewal costs for concrete- and wood-tie track for four specific test cases and traffic ranges from 15 to 40 annual million gross tons (MGT). The sensitivity of the justifiable first cost of concrete ties as a function of parametric changes in service and maintenance variables has also been determined.
