Looking to go from Ely to Edinburgh on a Sunday morning in November, more than 12 weeks away so no full details yet, but I notice that at this time of year there are a few jouneys which take between 4-5 hours, but towards end of October there are less and can take around 7 hours.What happens to timetable at that time and is it more practical to go via London rather than Peterborough in the autumn?
