If HS2 had fully gone ahead with newly built lines to Wigan and York, could crew changes at Preston and Newcastle been eliminated, or would journey times still have been too long for that? I know it's not massively common, but two of the 50+ minute delays I've had in the past year have been because of a need to wait for train crew at Preston or Edinburgh, and although better reliability of HS2 has come up as a benefit (newer infrastructure) I don't remember train crew management being mentioned at any point (I'm not saying that it hasn't). So could HS2 have improved the situation?
