I honestly believe they'll be a large push for DOO. I think the Train Managers for TOCs such as CrossCountry have a fight on their hands.
If cuts are to be made I suspect now would be the ideal time especially in the light of low passenger numbers.
Maybe I'm over thinking it but I suspect not.
I think the InterCity train managers have less to worry about. West Coast in calcuations done a few years back actually came back as making a loss over 20 years if DOO was to be implemented. XC is an odd case though as it has tiny trains absolutely stuffed with staff on above average wages. A 4 car voyager with a driver, train manager, retail service manager and first class host is very expensive to operate.
