Watford Junction to London Euston

Hi All,

I'm considering moving to Watford, and I just wondered if anyone knew
how much an Annual Season Ticket from Watford Junction to London
Euston is?

Thanks!

I have to admit that I haven't closely followed the discussions about
Watford Junction, but I understand that you can use PAYG from there, can't
you?

If that is indeed the case, then can you take a fast train between Euston
and Watford Junction, rather than just be restricted to the Overground?
