I swear the fellow doing the announcements at Euston keeps talking
about the "London Underground service to Watford Junction". I could be
mistaken given the similarity of the names and the poor quality of the

They do seem to say "London Nngground" very indistinctly, and I expect
that this is perceived as "Underground" because it's the expression
that everyone is used to. Or maybe they are hedging their bets.
