There's a Section 4 opportunity at Manchester Airport on Thursday morning which prevented it running the full week.Thanks all. Utterly random services! Even down to the 2212 ex Edinburgh not going to the Airport on a Wednesday, but doing so for the rest of the week, and yes it was the 2101 from Glasgow to Preston which called at Penrith (2257) which ran non stop to Preston, and not the later Edinburgh to Manchester (Airport sometimes) service.
Something I did notice is that there is an Avanti 1A10 Monday-Friday that is booked to call at Hartford (suppressed at the moment). 1A18 does the same on Saturday.
