Locomotive Crash Energy Management Vehicle-to-Vehicle Tests 1 & 2: Analyses and Test Results
Crash energy management (CEM) components which can be integrated into the end structure of a locomotive were developed: a push-back coupler and a deformable anti-climber. These components are designed to inhibit override and improve crashworthiness for equipped locomotives in a wide range of...
Modeling Track Mechanical Behavior with Under Tie Pads and Under Ballast Mats
Under the sponsorship of the Federal Railroad Administration (FRA), researchers at the Volpe National Transportation Systems Center developed a finite element (FE) track model to understand track mechanical behavior with pads and mats. The track model used monitoring data gathered during the...Railworthiness Directive for Certain Railroad Tank Cars Owned by Sumitomo Mitsui Banking Corporation Rail Services (SMBC) and Equipped With SMBC-owned Rubber Linings
Note: A Federal Register Notice regarding this Railworthiness Directive was published on July 25, 2023. Click here to access the Federal Register webpage.
Fully Scalable Train Braking Simulation Environment
Transportation Technology Center, Inc. (MxV Rail), through a research project funded by Federal Railroad Administration (FRA), developed a Concept of Operations (ConOps), documented the infrastructure design, and developed software to support a virtualized fully scalable train braking...Unsaturated Characteristics of Fouled Ballast to Support in Situ Identification of Fouling Using Ground Penetrating Radar – Phase II
The Federal Railroad Administration funded researchers from Kansas State University and the University of Arkansas to establish the electromagnetic, suction, and strength characteristics of fouled ballast as a function of the fouling material and volumetric water content. The team previously...Development Length Variables in Pretensioned Concrete Ties
This research, conducted from 2011 to 2015, is part of a larger project, “Quantifying the Effect of Prestressing Steel and Concrete Variables on the Transfer Length in Pretensioned Concrete Crossties,” conducted by Kansas State University (KSU) and sponsored by the Federal Railroad...
