But last week the Paddington-to-Swansea (M4 corridor) train gained notoriety as the blabbermouth express when staffers at one agency decided not only to discuss the pitch they were on their way to - but to prepare for it with a plethora of loud calls to the press, sounding out views on their potential client.
'It was embarrassing - it was very Ab Fab,' PRWeek's spy on the train tells us.
Shelly Sofier, MD at the offending agency - The Grove PR Consultancy - defended her loudmouths. She tells us: 'It was nothing confidential, we would never discuss something confidential in public.' It is not the first time pitches have been overheard on the Paddington train - PROs be warned.
Israel uses reality show to find PR star The latest show on the reality TV block takes us to - of all places - the Middle East, where 14 shiny young faces are competing to become a spin doctor for Israel.
The winner of the show, called The Ambassadors, will scoop a top PR job promoting the country in the city of New York.
The 14 contestants are to battle it out by seeing who can portray their homeland in the most positive light - and judging their performances is a panel of former Israeli army spokesmen.
The show is intended to explain public confusion about the Israeli-Palestinian conflict. Natalie Appleton, who quit British reality show I'm a Celebrity... Get Me Out of Here! earlier this week, should, we assume, steer clear.
