Ok so we know that if the maximum journey time is not exceeded when using Oyster PAYG, then the fare charged depends on where one touches in and out.
On "Loop" services on TOC's, such as the Kingston or Hounslow loop on South West Trains, would it theoretically be possible to:
*Travel the Long way around the loop, say for instance starting off at Hounslow, touching in there, taking the train via Twickenham to London Waterloo and then taking another Hounslow loop train back from Waterloo to Isleworth via Barnes Bridge. Then only getting charged the Oyster fare of Hounslow to Isleworth (1 stop £2 peak/£1.60 off peak z4-5 fare)?
I have always wondered how this is approached by RPI's, if say the person doing it was checked on leaving Isleworth but the train they came off was seen coming from the London direction rather than the Country direction where the original touch in was at Hounslow. I know that if checked on the train the "touch in" must be taken as valid unless the max journey time has meant that the journey expired.
Could it be seem as an MG11 case of attempting to avoid the fare, or is the long route around the loop valid regardless of the other zones passed through but not paid for?
The Oyster system on loop trains is something that fascinates me, I think it shows how smartcard systems can be open to abuse and that Oyster has little facility to consider the route taken when charging a fare!
