I'd agree that's probably the least unuseful (!). The case for Bakewell is very poor indeed, you would be building a whole line* just to serve Bakewell, as if you want a through service from Manchester to Derby it is already possible to do it as a portion of either the Norwich or the Cleethorpes, the fact it isn't being done would suggest it's not viable to do it, particularly as the Project Rio Manchester-London service ran for a bit so tested Manchester-East Midlands demand, albeit 20 years ago now!
* As East West Rail has demonstrated, a reopening of this nature is basically new build, it's just easier to acquire the land. Most underbridges have been replaced on that for instance.
*Perhaps that's one of the problems with our way of building railways.
There seems to be a market for travel between the North West and East Midlands. Sheffield certainly seems the long way round.
