And one thing to watch out for, Network Rail often leave the barriers open,
inviting you to just walk though whilst forgetting to "swipe" your Oyster -
and then the ticket inspector does you for a penalty fair on the train!

But, would you need to swipe if your Oyster card is loaded with a
Travelcard?

You wouldn't, but occasional users are much more likely to be using PAYG
than a Travelcard.
