There's probably have been little demand for trains going through Midland non-stop, north-south ones would go via the Old Road, and from what I can gather cross-pennine charters/excursions normally went via the Woodhead route rather than the Midland, but as said above would normally have had a loco change at Victoria, though I'm sure I've seen a footex with a pair of 37s at Woodhead tunnel. Even if they'd have been routed via Midland there's a good chance they might have had a crew change there, and Sheffield was known as a point to get stopped and pick delay up back before The Crucible was even built, there's a driver complaining about it in 1969's "Engines Must Not Enter The Potato Siding"!
