Hi I am wanting to go from Wymondham to London this Sunday but need to be in London before 11am. So the plan is to start my journey from Diss but still buy a return to Wymondham for the return leg. Is this allowed? When I am on the Greater Anglia site, I select a train that leaves Wymondham at 9:57 so will this be printed on the ticket or is it simply an off peak return to use at any time of the day? Thanks in advance!
