Going back to the original yellow 'interchange validators' having thought it
through again. *With extension to the NR routes they do actually become a
major PAYG loophole don't they. Your previous suggestions about a 'soft
exit' cover the situation. Transfer from LU onto SWT at Wimbledon with a
touch on an interchange validator and the system will treat that as your
exit - if you then don't touch out on exit at an ungated station further
down the line *you've saved a few zones. *So perhaps most of them will be

Yeah, you see where I'm coming from on that point.

But is it really any different from any other situation of travelling
without a valid ticket? If you were determined to use that kind of
"loophole"*, you could still touch at the wide gate.

*It's not really a loophole, because it's simply travelling without a
ticket and, if you are gripped, you pays the price.
