Rail Wheel Noise in Road to Rail Maintenance of Way Vehicles
… same railroad tracks used by trains. Thousands of these vehicles are used to regularly inspect and maintain the infrastructure that keeps the North American economy running. A common complaint when operating these vehicles when traveling on rail is an excessive wheel noise at 29 MPH. Because …

Development and application of a probabilistic risk assessment model for evaluating advanced train control technologies
… probabilistic rather than statistical assessment of safety improvements achieved with advanced train control technologies. This probabilistic assessment is performed through fault-tree analysis of four accident categories: head-on and rear-end collisions, track-fault-related derailments, and …

Application of Optical Detection Methods for Top-of-Rail (TOR) Lubricity Evaluation on a Moving Platform for Revenue Service Track
This research serves to evaluate the ability of optical detection techniques to ascertain the lubricity of revenue service track from a moving platform for railroad applications. A literature review is presented that covers the rail vehicle dynamics that drive the need of Top-of-Rail lubrication …

Flexural behavior of prestressed concrete monoblock crossties
As the use of concrete crossties increases for heavy-haul freight railroad lines in North America, it is becoming more critical to improve the understanding of their flexural behavior. This improved understanding can help to optimize current design and maintenance practices for concrete crossties, …

Investigation of aggregate properties influencing railroad ballast performance
A large portion of the annual budget to sustain the railway track system goes toward the maintenance and renewal of ballast. Railroad ballast is a uniformly-graded coarse aggregate placed between and immediately underneath the crossties. Large variations in the source properties of new ballast …
