At Sheffield the displays show:
TPE - "Express to Manchester"
Northern - "Stopping service via Hope Valley"
If the Northern services had a false destination of Reddish North (or wherever) people holding Advances to Manchester would likely be confused.
Similar with Leeds trains. "Fast via Barnsley" is shown and the stoppers do not have a false destination of Woodlesford.
I do not see why something similar cannot happen at York.
