It was challenged and it didn’t happen hence why all the cross country trains still stop and there was no service disruption! There are 2 passenger trains that do not stop at Stockport per day one is the first cross country from manchester as it takes a different route everyday due to driver route knowledge retention the second is a buxton to manchester service that is express hazel grove to buxton as it is “too full” by hazel grove hence why an East Midlands train from Nottingham stops 3 mins behind it to pick up extra passengers at hazel grove! I have worked on the railway 30 years almost think I’m qualified to know what does and doesn’t go on!
