As somebody who travelled out of Padd endlessly in those days, here are a few more bits of info.
The Leeds/Hull train was replaced by a Padd - Llandudno, but this only ran during Summer 86, thereafter the "Cross Country" turns went no further north than Brum/Wolves, although the winter 88/89 timetable saw the 0600 from Padd on a Saturday go through to Manchester. After this point, NSE based locos became the norm, which provided great interest for the Birmingham New Engine men, as even the 47/4's that worked these were "rare" over the Cov - [stn]BHM[/stn] route.
The High Wycombe run tended to produce 50's more often than 47's, based on photos I have seen and personal experience. There were plenty more interesting Mon-Friday turns, as virtually every other departure in the rush hour was hauled - there were turns that terminated at Maidenhead and Twyford, something unthinkable now.
And then, of course, you had the interlopers. 31424/405, 47368 and 47340 were all out on 22nd July 89, due to a major motive power shortage at Old Oak. Have a look at my website:
