Two methods are presented to determine the optimum spacing of hotbox detectors. In both methods, optimum spacing is determined by economic factors, as well as other considerations. Growth or decline of traffic, changes in types and values of commodities hauled, changes in operating practices and changes in locations of car inspection points, all have a bearing on the results obtained from hotbox detectors. It may be desirable to change locations of detectors to fit new operating and/or traffic patterns. The increasing use of roller bearings must be taken into consideration when locating hotbox detectors. There is a short lead-time between the start of heating in a roller hearing and the presence of a critical case of a broken journal possibly within a distance of 30 miles or less. A good record should be kept of hotbox occurrences, set-offs and derailments, including costs, to determine if the study results are producing savings and reductions in hotbox set-offs and derailments due to hotboxes.
