FIRST PROGRESS REPORT OF THE COMMITTEE ON HOT BOX ALARMS

The object of the tests was to determine whether a device exists or might be developed which can effectively warn the train crews of the danger of a hot box. As a result of tests it was determined that the sensitive element of the device must be located in the bearing or the journal itself. The alarm should be sounded at a bearing temperature of approximately 350 degrees F for plain bearings. No one type of sensitive element or means of transmission was found superior to the others.
