On recent travels over the last week I've noticed two Virgin services that I can't find anywhere in their printed timetables. One was a weekday London-Birmingham service leaving MKC at 10:13 that continued all the way though to Glasgow Central. The timetables show it as terminating at New Street (not even Wolverhampton, where it did call). The other was a Euston-Edinburgh service calling only at Preston which I spotted at Euston at around 11.15 (it was leaving at the time). Does anyone have any idea why these services aren't in the timetables and/or if there are any other ghost services like them?
