None of the problem areas I know of will see the new trains.
That was rather my point. If only the new trains are equipped for DCO/DOO, and none of the new trains will operate in areas which are a problem, then there isn't a problem since DCO/DOO can't happen in those areas. I would have thought that was obvious.
I prefer to base my opinions on experence.
And I fully respect your experience, but experience isn't the same thing as evidence. If I put my journalist hat on for a second, if I imagine I was producing a report on the RMT strike action, and an RMT rep says to me that DOO/DCO is unsafe, I have to respond by pointing out the RSSB/DfT evidence which says the opposite. It doesn't matter how many individual examples from experienced drivers or other staff the RMT give me, they don't carry the same value as researched, evidence-based, studies published by professional bodies (not saying the RMT is unprofessional, but you know what I mean).
If they want to play the safety card, then rather than just saying the the DfT evidence is wrong, RMT need research of their own need to prove it.
I'm no fan of the RMT. But they have a valid case until proven otherwise with the safety element in the North.
Proving the complete safety of a way of working is always going to be impossible, and so can't be the threshold, no matter how desirable it might be. Instead, the threshold has to be whether any risks that are discovered through a thorough assessment can be mitigated to a level where the residual risks are considered acceptable. Unfortunately, agreeing what 'acceptable' means is always going to be 'challenging'. For me, if the risk of my being killed or seriously injurred on the railway is the same or less than it is when I'm driving, I'm happy. That is, after all, where I'd be if I wasn't on the train. My understanding of the evidence is that, DCO/DOO or not, the risk to my safety on the railway is actually very much lower than that, and therefore completely acceptable in my book.
