WIDE GAGE INVESTIGATION. VOLUME 2
The wide gage investigation involved test measurements in the summer and winter months. The reasons for performing measurements by season was because experienced railroad engineers felt the phenomena of gage widening was accelerated during winter months. As reported in Volume I, permanent widening of gage occurs in the summer. Significantly, no appreciable permanent track deformation was found in periodic gage measurements at the test site between May (the installation of the test sections) and November of 1974. After a sufficient period of snow and subzero weather had passed, to assure that the ballast section had deep frost, the track dynamics instrumentation as described in Volume I was again set up for measurements. This report presents the results of this winter series of experiments.
