Standardization for intelligent detection and autonomous operation of non-structured hardware, and its application on railcar brake release operation
… of automating emergency brake release before rail-car decoupling. A significant hurdle to be accounted for is the lack of standardization of much of the hardware of interest in industry. Non-standardized rail car components must be formally structured as fully as possible to improve the …

Axle burn-off and stack-up force analyses of a railroad roller bearing using the finite element method
Railroad bearing-related failures are a primary concern to the railway industry. A bearing-related failure can cause derailment and result in millions of dollars in damage. The bearings used in railway applications are almost exclusively tapered roller bearings and are composed of a two-row …

Active suspension co-design for lateral stability of rail vehicles
Railroad transportation is one of the most cost-effective and energy-efficient modes of land transportation. With an eye toward improving these efficiencies, many efforts have focused on developing high speed railways. Traditionally railways have utilized passive suspension systems, but maintaining …
