This study investigates the decision-making process for railroad track maintenance (T/M) expenditures. The objectives are to (1) describe how Federal track safety standards have influenced this process and (2) try to predict the impact of changes in safety regulations on T/M spending for all U.S....
This report covers research that was performed to investigate the present crashworthiness state of in-service locomotives and design applications for new locomotives to protect occupants from serious or fatal injury during collision conditions. The tasks that were performed are: (1) identify past...
[From the Introduction] To comply with the provisions of 49 CFR 225, all railroads are required to file monthly accident/incident reports with the Federal Railroad Administration's (FRA) Office of Safety. Bulletin 150 summarizes all reportable railroad accidents/incidents that occurred in the...
This report presents the findings of the joint venture demonstration training project conducted by the Louisville & Nashville Railroad and the Brotherhood of Locomotive Engineers. Volume I contains a survey of the literature, a job task inventory and a set of guidelines for instructional...
Vibration tests of fireproof coatings were performed on test specimens measuring 4 feet square. Specimens were simulations of railroad tank car side- wall panels. Samples of fireproof coatings from three different manufacturers were tested. The vibration test consisted of application of a...
The Federal Railroad Administration is to perform a parallel effort of test and analysis of a 70 ton boxcar configuration. The program objectives are to develop and demonstrate a validation procedure, to provide an analytic capability of predicting accurate over-the-road boxcar response...
This report documents the results of a vibration measurement program conducted on 14-15 August 1980 in the Midwood Section of Brooklyn, New York, next to the tracks of the Brighton Line of the New York City Transit Authority. The test was conducted by the Transportation Systems Center (TSC) for the...
This is a user’s manual for two versions of a computer program to calculate the dynamic response of freight cars to track inputs. The basic program is nonlinear, written in FORTRAN for Control Data Corporation (CDC) computers with solution in the time domain by numerical integration methods. The...
The SPAR program, originally developed by W. D. Whetstone, is an analytical system for calculating static deflections and stresses, natural vibration modes and frequencies, and buckling loads and mode shapes associated with linear, finite element structural simulations. This Report extends the...
SPAR 11 is a version of Level 11 of the SPAR program, as modified and enhanced for the Association of American Railroads. The enhancements are in the area of interactive use and graphics on the DEC-2050 computer. This user's guide does not replace the SPAR Program Manual, but has instead the...
