They have 'validators' on the platform (Think Oyster Card Pads without

So presumably on-train ticket examining staff will need oyster card
readers?

Not necessarily - they can put gates on all of the other stations on the
line so you would have to validate to get off anywhere but Watford.
Therefore if you wanted to be charged the correct fare (or get out at these
stations) then you would make sure you had swiped in at a Watford Junction
validator.

Similarly if you did not validate when you got off at Watford Junction then
you could be overcharged for your journey.

Notwithstanding the above, on-train staff already have oyster card readers
in the SWT area, so it's not a new concept.
