In its programs and efforts in the field of rail research, the AAR Research and Test Department is continuing the study and analysis of those rails that continue in service which show some potential for improvement in performance. Rails that are heated-treated, have a variance in chemical composition from that of standard rail or which are unconventionally produced come under this study. The scope of this program of field inspection and analysis is to observe those rails in curved track that display greater wear resistance and the quality of retarding the advent of shelling. This report is divided essentially in two sections. The first section covers the inspection of four service test curve installations on the Burlington Northern, Inc. (formerly the Great Northern Railway) between Glacier Park, Mont. and Seattle, Wash. These are, namely, curves 125, 133 and 136 between Blacktail and Nimrod, Mont., curves 705 and 710 near Camden, Wash., curves 48 and 52 near Winton, Wash., and curve 89 near Berne, Wash. The reporting on these installations is in narrative form, generalizing on the condition of the rails in the curves as a whole so as to conform with the reporting format of previous inspections. The second section covers the inspection of three installations on the Burlington Northern, Inc. (formerly Great Northern Railway) near Superior, Wis. and Carlton, Minn. These are No. 1 lead track curve in Allouez, Wis. yard, curve 20 near Carlton, and curve 22 near Carlton. As was done in the previous reporting format of curves 20 and 22 and to conform to that format, this report lists each of the rails in each of these curves in tabular form, giving results of this and the two prior inspections for comparison.
