FRA is issuing this Second Supplement to Safety Advisory 2023- 01 to reiterate and expand upon the recommendations in its previously published Safety Advisories related to hot bearing wayside detectors (HBDs). This Safety Advisory reiterates FRA's previous recommendations in Safety Advisory 2023-01 and its June 14, 2023 Supplement, and expands on the recommendations to incorporate the findings of FRA's ongoing evaluations by emphasizing: the importance of trend analysis and the opportunity to integrate wayside detector data types to evaluate railcar health; the need to establish and follow appropriate processes in analyzing and responding to HBD data; the need for railroads to ensure that adequate staff are assigned to monitor and respond to wayside detector data; and the need for railroads to maximize the use of HBD data, including sharing wayside detector data between railroads, as a train travels from one railroad's tracks to another railroad's track.
