Muz ...if you know better than the safety experts, why dont you apply for a role as one......?
you dont need to be a safety expert to realize that in the two main situations I have identified there is an increase in risk between having a driver and guard and having a driver only . Its just common sense to anybody that knows even the slightest about railway operations in those area
Playing devils advocate you could accept that there is a risk increase in place with DOO and yet still argue in favor of DOO by saying the likelihood of a driver being incapacitated or a situation requiring an emergency evacuation is that minute that we can accept the risk and mitigate it with the technology we now have ,as well as dispatchers and emergency stop plungers on platforms.
I think where you are getting mixed up is in thinking that it is my opinion that there is an increase in risk factor from DOO when that is just a cold hard fact , even the people carrying out risk assessments that led to the current DOO have to acknowledge that increase in risk . How do you think the LU emergency stop plunger or the deployment of dispatchers mirrors and cctv at DOO locations comes about ?through an acknowledgement that there is more risk from a driver carrying out dispatch and a need to mitigate that risk . That is not my opinion that is the facts of the matter . The risk assesments that would have been carried out to approve one man operation on the gospel to barking line must have been staggering . And would have taken into account the increased risk at the platform train interface and an emergency between stations . Just so happens that the risk assessors where satisfied with the measures put in place to control those risks . Well they where paid to be satisfied with the measures anyway
And one of the snags with DOO being implemented on the northern network is the need to carry out all of this investment and modify stations and traction to mitigate those risks . If there was no increase in risk northern could have deployed DOO already and would have done so because operationally it means there is less chance of cancelling a train due to staff shortages and it lowers operating costs .

The Majority of the DOO was done in the late 80s and early 90s when BR was in dire straights. If DOO was so successful why hasn't it been expanded rapidly in 20 years? quite simply infrastructure costs do not make it worthwhile in the Majority of areas outside the South East. Its not as if a line has been reopened to certain specifications. Up here we still have a heck of a lot of AB and semaphore signalling many platforms are either very low or with a big gap. Spending on platforms have been minimal to say the least. My opinion is quite bluntly it may be in the prospectus but it would cost network Rail Billions of pounds to upgrade the Network enough to make DOO feasable. I will be very surprised if it is implemented in the next decade at least.
This - the vast swathes of DOO that people expected post privatization didn't happen because a franchise is generally not long enough for the TOC involved to put the investment in and reap the rewards and the gov wasn't interested in wholesale investment in the network .
As a result the investment that is now needed isn't to implement DOO its capacity upgrades and rolling stock replacement -can anybody say pacers .
I dont think that the traveling public are going to care or thank the gov for implementing DOO in order to reduce the subsidized operating costs if they are still traveling around on overcrowded , delayed legacy rolling stock .
