Thanks very much for the summary HT - that has saved me some work. Would you mind if I used this in correspondance with the transport companies?
It is worth noting that the EYMS timetable shows arrival and departure times at Barton Interchange.
On Sundays the 13:20 from Paragon arrives at Barton at 13:52, thus giving a 7 minute connection rather than the 2 minute connection the combined timetable suggests. I am not sure whether this 5 minute dwell at Barton is deliberately intended to allow the bus to make the train connection - if it is then good on EYMS.
