I imagine most of the capacity on that route is provided by CrossCountry. Anything that takes passengers off their services is a good idea as far as I'm concerned, given how overcrowded they are.
Do you mean that EMR should take passengers off CrossCountry because their services are overcrowded or vice versa? There may not be an inherent need for direct Leeds - St Pancras services in addition to Leeds - Kings Cross, but there could certainly be a need for increased Sheffield - Leeds capacity provided by extensions of the St Pancras - Sheffield services.

The purpose of the new Castlefield timetable is to prune the service enough that the overcrowding is reduced and delays don't cause knock-on effects to the notorious extent they do now. If it's successful in that regard, I really hope they just leave it alone and stop messing with it until/unless the improvements at Piccadilly and Oxford Road (planned, since mothballed) go ahead.
I think Manchester needs the Corridor to work reliably more than it needs one train per day from Adlington to Adlington!
I agree with the sentiment of simplifying the service pattern through Castlefield in order to mitigate the current issues, but I find that the MRTF option B+ will be unworkable in the long term and need recasting again due to the number of compromises made. By all means run a standard half hourly pattern through Manchester, but with maximum local connectivity at either end.
In particular the Southport service cannot terminate at Oxford Road since reversing at Oxford Road has a larger adverse affect on capacity than running through and connections to/from Piccadilly will be made very difficult. I don’t know why they can’t run a clockface half hourly Bolton - Manchester Airport with one extended to Blackpool North with a double 331 and one extended to Southport with a 769, even if the Southport service was given the all stops path to the Airport, given that there will be a clockface half hourly CLC - Hope Valley service giving Warrington Central - Sheffield connections, but run by TPE with 185s and 68+Mk5a sets and extended to Cleethorpes and by EMR with 158s and even 156s and extended to Norwich. There is no need for a 2tph Blackpool North - Manchester Airport. The 2nd Blackpool should run to Hazel Grove, which will be left without an electric service.
I don’t see why the Stoke-on-Trent stopper should run via Castlefield and it doesn’t, but the one train a day from Adlington to Adlington runs early enough in the day so as not to disrupt things too much. I believe that the MP for Bolton wants a through Pendolino from Bolton to Euston via Castlefield, which would not be able to call at Piccadilly. That is exactly the kind of extension that resulted in the mess we’ve found ourselves in.
Melton Mowbray and Oakham have just one service each way to London St Pancras provided by EMT, neither of which seem to run at times when most people would want to travel. Presumably this is primarily a route knowledge trip for EMT drivers on the rarely used section between Corby and Manton Jn?
The Melton Mowbray - St Pancras service including the rare track between Corby and Manton Junction was one I mentioned in my original post!
I have also remembered that Skipton has 1 train a day to Kings Cross which is run by a 91 in the morning.
