Neatly dovetailing into this thread, I've noticed this. NRE is showing disruption between Chinley & Edale, due to a tunnel inspection that is affecting Northern, TPE and EMR services. However, EMR services are not running between Sheffield and Stockport, due to planned engineering - according to EMR twitter.
NRE also states that EMR services are only operating between Sheffield and Norwich, but EMR state that train services are not operating between Nottingham and Ely, again due to planned engineering work. So my point is, how are everyday passengers supposed to know or understand when conflicting information is being supplied.
