When I sometimes goto City of London ,I would buy a London Terminals ticket and avoid having to get Tube by using it to get overground to London Bridge. All legal as ,for historic reasons ,London Terminals means Waterloo or London Bridge.

However , my Flex tickets are bought on a SWR smartcard and don't work on London Bridge gates. Are those Flex tickets different in that they are only to Waterloo ? Can I use my flex tickets to London Bridge. NB I noticed that my smartcard gets me onto Waterloo East barriers so that it is weird as it won't allow me out at London Bridge.

Any ideas ?
