The Federal Transit Administration’s (FTA) Public Transportation Safety Program includes two separate requirements for training:

• FTA’s Public Transportation Safety Certification Training Program regulation, 49 CFR Part 672, specifies “a uniform safety certification training curriculum and requirements to enhance the technical proficiency of individuals who conduct safety audits and examinations of public transportation systems and those who are directly responsible for safety oversight of public transportation agencies.” (§672.1(a))
• FTA’s Public Transportation Agency Safety Plan (PTASP) regulation, 49 CFR Part 673, requires each covered public transportation agency to “establish and implement a comprehensive safety training program for all agency employees and contractors directly responsible for safety in the agency's public transportation system.” The training program “must include refresher training, as necessary.” (§673.29(a))
