I am pleased to see this thread attracting contributions from folk 'at the sharp end', real 'interested parties' not like me not much more than a crayonista rail enthusiast who is 'interested'.
I had to look up PTI, to find it's Platform Train Interface, and the first website it took me to is this, Undated:
https://www.rssb.co.uk/about-rssb/key-industry-topics/platform-train-interface
Is this current? Does the RSSB (Rail Safety Standards Board) still exist?
Considering the possibility of 'level boarding' at Old Oak Common GWR platforms, similar issues arise on a related thread:
https://www.railforums.co.uk/threads/old-oak-common-level-boarding-for-elizabeth-line-trains.297832/
Bearing in mind that the Rail Accident Investigation Board must surely be aware of boarding-related 'issues' at Ealing Broadway is it not 'surprising' that more weight was not given to this aspect.
The RSSB website cites PTI as being the most significant factor in fatalities.
Sadly, the RAIB report does indicate 'issues' regarding the driver's record. and surely this too could have been a contributory factor to their wish to make progress and closing the doors while passengers were stil alighting as well as seeking to join what was the last train.
The RSSB gives (gave?) a lot of attention, rightly, to the PTI and issues of behaviour, control, etc. Was this just so much 'hot air'?
At Ickenham a man DID die:

This MUST be a matter worthy of greater attentiom at the highest levels, including in parliament and government; I look forward to hearing ... while not holding my breath.
