The test series included measuring the temperature of a railroad journal assembly during actual operation, reproducing field conditions in the laboratory for sensor development testing, and testing the thermal sensor in actual use. Normal operating temperature, over-heated bearing temperatures, and several journal surface temperatures were measured during field operation. The data obtained was used in determining the subsequent laboratory test parameters. A hot plate temperature test was used for testing the sensor in the early stages of development. Existing laboratory facilities were modified to provide simulated field temperature inputs to a partial side frame and journal assembly for confirmation tests. Data from all field and laboratory tests is included. (DePo)
