This study includes a review of European Union (EU), US and Asian standards, codes, and regulations related to high speed rail. Key results include: 1) a detailed survey performed on the topics of global standards and regulations for transportation noise with a focus on high speed rail...
Transportation Technology Center, Inc. conducted an impact test with two F40 locomotives to evaluate the performance of both vehicles under dynamic conditions. One locomotive was retrofitted with crash energy management (CEM) components including a push-back coupler (PBC), deformable anti-...
Transportation Technology Center, Inc. conducted impact tests with a Budd M1 passenger car and an F40 locomotive to evaluate the performance of both vehicles under dynamic conditions. The locomotive was retrofitted with crash energy management components, including a push-back coupler (PBC) and...
Researchers at Michigan Technological University used Second Strategic Highway Research Program (SHRP2) naturalistic driving study (NDS) data and a driving simulator to perform a quantitative evaluation of driver behavior at highway-rail grade crossings (HRGCs). They developed a 3-point scale to...
From April 5, 2019, to August 20, 2020, the Volpe National Transportation Systems Center (Volpe) performed a series of finite element (FE) analyses of uniaxial tensile tests to calibrate material models for tank car steels (TC128) from two recent side impact tests. The material models, which...
From February to April 2014, Transportation Technology Center, Inc. (TTCI) performed research and testing on a broken rim detector concept by Diesel Intellect International (DII). The detector uses proximity sensors to detect the presence of rim material overhanging the field side of the rail....
The U.S. Department of Transportation (DOT) John A. Volpe National Transportation Systems Center, under the direction of the U.S. DOT’s Federal Railroad Administration, Office of Research, Development, and Technology, evaluated the impacts of a program for four law enforcement agencies to...
The Federal Railroad Administration (FRA) conducted a side impact test on a DOT-111 tank car at the Transportation Technology Center (TTC) to evaluate its performance under dynamic impact conditions, and to provide data for the verification and refinement of a computational model. The tankcar...
With the development of new lighting technologies, such as light-emitting diodes (LED), the safety requirements stipulated in 49 CFR §229.125 may not adequately accommodate the introduction of LED lamps to the railroad industry. Consequently, it is necessary to better understand the current...
This report describes Phase I compliance testing of light-emitting diode (LED) fixtures as locomotive headlights and auxiliary lights. The purpose was to validate that all LED samples submitted by participating suppliers complied with applicable regulatory requirements and standards, and to...
