It may not qualify as the "not too distant past" but I do remember at least one London train stopping at Congleton pre Virgin. Perhaps it was because I tended to travel at the same time of day - but it seemed that every train I was on (between Stockport and London) stopped at Congleton in each direction. I also seem to recall that there was an issue with platform length and I also seem to recall a level crossing (no longer there) being blocked by the stopped train.
Locally, I think the OP perhaps should have asked which stations deserve more trains per hour - in which case Knutsford with 1 tph (each direction) with over 500,000 pax p.a. must be up there!
Edit - Just seen Deltic's second post - these were likely to be the trains I used.
Edit 2 - Out of interest I looked at Wikipedia and it says "The line from Stoke to Congleton was opened on 9 October 1848, with Congleton station opening on the same day and owned by the
North Staffordshire Railway.
In early privatisation,
Virgin Trains served the station every two hours during the day, Monday to Saturday, as was agreed by
Virgin Trains to prevent increased use of the line by stopping services. " If it was early privatisation, it would be more likely to be VTWC rather than VTXC, but I stand to be corrected.
