In his report, senior coroner Graeme Irvine said that in the two years since Mitchell’s death, “there is no clear evidence to demonstrate that risks of fatal harm have been mitigated”.
He said: “Recommended technological measures to detect and alert staff to the presence of persons on the tracks have not been implemented at Stratford station.”
Irvine added that there was no clear data available to demonstrate that train operator and station staff training had improved performance in emergency circumstances.
He concluded in his report to Sir Sadiq, TfL and the Department for Transport: “In my opinion, action should be taken to prevent future deaths and I believe you have the power to take such action.”
