Cough Free Coaches - Daily Mail - 14/12/2005

Rail commuters are being given the chance to give coughing companions the cold shoulder, it was revealed today.
Travellers with London to Essex coast train company c2c are from today getting a cough-free carriage to escape the germ-spreaders. Any passenger showing the first sign of a cough will be politely asked to move.

The carriage will operate until April 2006 and has been set up by cough medicine company Benylin.

The initiative followed a survey by the company which listed people who cough as one of the top 10 pet hates of rail travellers.

A spokesman for c2c told the London Evening Standard: "You get thoughtless people who either insist on travelling and spreading germs when, for the benefit of all, they should have stayed at home.

"We think our special carriage will be very popular".

The poll, of 1,137 people, showed 47 per cent would welcome a "cough-free zone" on a train, with 28 per cent saying they would move to escape from a coughing fellow passenger.

Commuters' top 10 pet hates were:

Stinkers
Seat takers
Loud music lovers
Smokers
Smelly food eaters
People with smelly breath
Bag ladies
Coughers
Snorers
Paper readers

The choke's on us
Carriage advert is a dream for c2c commuters by Mike Miners

Long suffering Essex Commuters can escape one of their pet hates in a c2c rail carriage where coughing has been banned.

Pharmaceutical giant Pfizer chose the line between Shoebury and London's Fenchurch Street Station to promote its best-selling cough medicine, Benylin, and the carriage that bears the sign has been designated cough free.

Alison Tyssen, of Pfizer Consumer Healthcare, said; "Cold and flu viruses travel through the air from a cough or sneeze and get into the body through the mouth or eye, meaning more people are at risk from coughs and colds.

The launch of the Cough Free Zone means commuters can travel in an environment where 'coughers' are outside of their personal space so they no longer have to concern themselves with a sneeze or cough face-on."

Pfizer say a new survey by Benylin revealed commuters are fed up with coughers disturbing them on their daily journey.

The survey found almost half (47%) of people would welcome a cough-free train and almost a third would move to a cough-free zone to escape a coughing fellow passenger.

The carriage was unveiled yesterday and will stay in place until April.

A c2c spokesman said;" We are open to approaches from other companies wanting to advertise on our trains.

"Any application will undergo a rigorous examination and one criteria is that it must be for our mutual benefit.

"Whether you have a cough or not you will still be very welcome this winter on our draft-free air conditioned trains."
