FRA Guide for Preparing Accidents/Incidents Reports

[From the Introduction] A railroad is required by 49 CFR Part 225 to use the current FRA Guide for Preparing Accident/Incident Reports when preparing its monthly report. The instructions contained in this publication are provided to assist railroads in meeting this obligation, and do not limit in...

FRA Guide for Preparing Accident/Incident Reports

[From the Introduction] A railroad is required by Federal Railroad Administration (FRA) regulations at Title 49, Part 225 of the Code of Federal Regulations to use the current FRA Guide for Preparing Accident/lncident Reports (“Guide” or “reporting guide”) when preparing its monthly report. The...

Finite Element Models, Validation, and Results for Wheel Temperature and Elastic Thermal Stress Distribution

This report is the third in a series of engineering studies on railroad vehicle wheel performance. Heat transfer finite element models of multiple unit (MU) power car wheels are documented and validated by comparison of calculated temperatures with measurements made during an operational test....

Final Report on Magnetic and Electric Field Testing of the French Train A Grand Vitesse-Atlantique (TGV-A) Rail Systems: Volume II - Appendices

The following 34 appendices contain a detailed reporting of the magnetic field characteristics measured onboard the electrified railroad and near associated facilities. The data have been consolidated and presented as efficiently as possible without resorting to summary measures which obscure the...

Final Report on Magnetic and Electric Field Testing of the Amtrak and Metro North Northeast Corridor and New Jersey Transit North Jersey Coast Line Rail Systems: Volume I - Anaysis

This report documents the low frequency electric and magnetic fields associated with the operation of the AMTRAK and Metro North Northeast Corridor (NEC) rail system. The study and data analysis was complicated by the existence of three different rail technologies along the existing route. The...

Final Report on Magnetic and Electric Field Testing of the Washington Metropolitan Transit Authority Metrorail System: Volume I - Analysis (DRAFT)

This report documents the low frequency electric and magnetic fields associated with the operation of the Washington, DC Metropolitan Area Transit Authority (WMATA) Metrorail (MET) Urban Transit System. With excellent cooperation and assistance of WMATA personnel, comprehensive measurements were...

A Physically Based Method of Enhancement of Experimental Data-Concepts, Formulation, and Application to Identification of Residual Stresses

This paper presents the formulation for a new approach to enhancing experimental data. Using simultaneously all the information available for the problem being studied, i.e, physically based approximation, this approach offers potential advantages over the typical methods used for fitting a curve...

Tilt Train Technology: A State of the Art Survey

This report presents a survey of the technical and operational features of existing and planned tilt-body rail passenger vehicles. It follows the general format of the December 1990 Federal Railroad Administration (FRA) Report entitled, "Safety Relevant Observations on the X2000 Tilting Train," (...
