Further to the documents you sent me from Question 2019/12001, I note that the 11 July 2017 Version of IA 17780 listed "Priority 1 issues" in the Executive Summary, stated:
• Tram Operations Limited (TOL) management of driver’s hours of work, and the roster design, do not consider fatigue risk factors or reference industry good practice.
• TOL’s fatigue awareness training for managers and supervisors does not include factors that increase fatigue or how to recognise fatigue in others.
• TOL has no formal process for determining when a fatigue risk analysis should be carried out or reviewed.
These priority 1 issues do not appear in any later drafts of IA 17780 or in the final version published on 15 September 2017. Please provide me with documentation which discusses the reasons why these Priority 1 issues were taken out of the document.
