Northern class 319 diagram's

Hi everyone.
Can anyone help me with any northern class 319 diagrams as i'm planning a trip over to the preston/ Blackpool area this week or maybe next week from county Durham and i haven't a clue where to go to see them. Thank you.

07:04 Preston to Manchester Victoria
07:05 Manchester Victoria to Preston

These are always formed of Class 319s on weekdays.

Edit: Come to think of it you could probably follow these diagrams forward to figure out more services throughout the day.

Hi there,
Thank you for that information, it's much appreciated!.
