What is the purpose of hot box tags and tempilstiks during inspections?

The purpose of hot box tags and tempilstiks during inspections is to monitor temperature and detect overheated bearings. These tools are specifically designed to identify potential issues with bearings, which are critical components of railcar wheelsets.

Hot box tags are used to mark cars that have been flagged during inspections for elevated temperatures, indicating that the bearings may be at risk of failure due to overheating. This allows for prompt action to be taken to prevent potential accidents or damage. Tempilstiks, which are temperature-sensitive indicators, provide a visual indication of whether a bearing has exceeded safe operating temperatures. By measuring and monitoring the temperature, inspectors can ensure that any overheating is addressed before it leads to more serious mechanical failures.

By using these devices, railroads enhance their safety protocols and equipment reliability, directly contributing to the overall efficiency and safety of rail operations.
