I was only answering a question as to what the TMs will do if they don't do the doors. They seem to do a lot on HS1.
I would always want a second member or staff on a train. I can only speak of my local experiance. They all have two members on board.
What use is a second member of staff, who won't have safety training etc, in an accident if the driver is smeared up the bulkhead?
If this gets in I would bet a year's salary that the guards safety critical knowledge will be gone within 2 franchise changes!
Neither FGW/DaFT have said anything to make me think otherwise, in fact 'that is a decision for the new operator' leads me to believe that the above is exactly what they are intending, otherwise they could they could put 'but we have no reason to believe that would be the case' and bearing in mind their love of using a thousand words but saying nothing makes it all the more iffy.
