Some detailed points which in some cases make it more complex for which I apologies.
There gets to be a point at which it's necessary to stop adding boxes for clarity and say "and others", and to leave out lines too. But let me comment further on your specifics.
I notice you only show one two way communication channel out of DaFT» to the ORR» . Is that deliberate or are all flows meant to be two way.
That has now been amended - and indeed I have added a couple of other "both way" enquiry lines too - I'll published a revised diagram later.
Also there appears to be no public interaction with DaFT again is that deliberate, it appears that all information received by DaFT is filtered through other organisations.
Apart from occasional and specific consultations, I don't think the
DfT» encourages the travelling public to get in touch with them over their travel issues ... Passenger Focus (for which they are the paymasters) is there for the public's "we're not getting what the DfT have requested" inputs.
You seemed to have missed off MPs▸ , who I know don't do much, surely they have direct input to DaFT.
I've added the bold because
I disagree with it, at least here in the Chippenham constituency. Without the assistance of Duncan Hames, I don't believe we would have got to where we are today. Other current MPs have been helpful too. Looking back to the previous parliament, the story was more patchy and indeed I had the feeling of lip service and not anything more in at least one case; that may be fair enough for an MP who's trying to remain in favour with a section of his electorate who ask him to help with a case that he feels in unproven.
You have also missed off peripheral organisatios that can have an effect on the provision of rail transport such as the road lobby and in particular bus indusrty which is seen as a competitor not a co-operator. Then there's English Heritage, Paddington Staion upgrade, Sydney gardens etc., English Nature SSIs▸ and HS2▸ . Maybe they could lumped in a box marked hostiles live here.
We could end up with a very complex diagram indeed ... and the box would NOT be marked "hostiles". Railfuture, Campaign for Better Transport, Campaign for the Protection of Rural England, and many other are wholly or broadly supportive, and almost all have positive elements however they may raised extra issues.
From my experience in a rail user group dealing with any part of the rail industry is like punching blancmange they can absorb a tremendous amout of requests for action without moving ...
Or you could call it "testing resolve" ...
