I know the merits of the GCML as a HS2 alternative and various what if the GCML hadn't closed topics have been discussed here and elsewhere. By asking my question I am not intending to stray into either.
What I am hoping to find out is which of the two routes afforded the quickest journeys to Nottingham and Sheffield prior to the closure of the GCML (and quite possibly prior to the focus of traffic on the MML).
