Statistical Representations of Track Geometry : Volume II, Appendices.
Jonathan C. Corbin, Ensco · ROSA P · 1980
This volume contains some of the more detailed data and analyses to support the results and conclusions reached in Volume I of this report. It is divided into appendixes lettered A through J. Appendix A defines a procedure for evaluating the statistical parameters from field-collected track-geometry data. Appendixes B and C contain track-geometry data traces and descriptive text used to support various results and conclusions as they apply to rail joints and track anomalies respectively. Appendix D contains the curve fits obtained for processed PSD data. Appendixes E and F describe the analyses used to determine instrument and quantization noise, respectively. Appendix G is a history of research preceding the effort described in this report. Appendix H describes formal mathematical procedures needed for complete characterization of a periodically modulated random process. Appendix I contains data on railhead wear. Appendix J reports on new technology.
