The article discusses a survey done to estimate the numbers of hollow-worn wheels in service and their distribution within trucks. The survey was designed to measure wheel profiles from the major car types in proportion to their percentage in the total fleet, and yards were targeted based on their relative volume of specific cars. An economic model was assembled to calculate the incremental costs and benefits of adopting different hollow-worn wheel removal criteria for the wheels. Results of the survey indicate that in addition to their effects on fuel consumption and rail wear, hollow-worn wheels are believed to contribute significantly to $350 million in annual maintenance bills for special trackwork.
