Bit confused....
I go to a ticket machine at (say) Finsbury Park (my local station). I buy a ticket from (say) London Bridge to (say) Hildenborough. How can that be open to fraud ?
Doughnutting.
That is (for instance) buying a CambridgeFoxton and a Finsbury ParkKing's Cross to operate the barriers at either end, and travelling all the way from Cambridge to London.
