DOR was sold to VTEC wasn't it?
And yes, how much the consortium is getting paid is going to be the next fascinating question.
It was the East Coast Mainline Co that was sold to VTEC, and which no doubt will become the vehicle that is branded LNER.
DOR (a group of DfT paid consultants) was wound up after VTEC started.
OLR will also be DfT paid consultants (hired from the different consortium partners) at the usual high daily rate (with profit).
They are not there to take risks, just to deliver the service.
The question really is what kind of "service agreement" they will get (performance, service enhancements, bonuses etc).
They will just run LNER, deduct the costs and pass the balance on to DfT, as DOR did.
DfT has published this analysis on the comparison between a VTEC direct award and using OLR.
Financially they are about even.
What seems to have swung Grayling to OLR is that Stagecoach/Virgin are now out of the planning loop for the future partnership.
