Presumably this means that some of the other improvements proposed in the consultation will have to be scaled back?
That's the worry.
If the Aberdeen service has to remain as it currently is (rather than using a Voyager off-peak at a time that may better suit the North Sea changeovers) then that ties one out of action (as far as the main XC route is concerned) until after 11:00 - which may mean there's no spare unit to do something like the Derby - Leeds peak service.
Retaining the additional capacity north of Edinburgh comes at a cost to the rest of the network (the 08:20 departure from Aberdeen taking until after eleven o'clock to leave Waverley - during which time a lot of people will have been standing elsewhere on XC).
There's a 07:52 HST from Aberdeen to Newcastle/ York, so it's not like the 08:20 is the Granite City's only link to England at that time of day - running a Voyager shortly afterwards doesn't seem essential.
