Hi,

Let's say I have a paper travelcard that lets me travel from zones 2 to 6
and Watford Junction.

Let's also say I need to travel from Euston to Watford Junction.

If I buy an Oyster prepay card and I touch in when going through Euston but
don't touch out (because when I get to WJ I use my paper travelcard), what
will be the repercussions?

TIA,
