Stood at Limehouse station this evening with the wind whistling round my blisters a non-stopping train whizzed past. My jaw nearly hit the platform when I saw the second carriage - bright orange/yellow with block red text COUGH FREE ZONE! (Exclamation mark mine).

Back in December someone mentioned c2c had introduced non-coughing carriages but I really didn't believe it. It was a gimmick; unworkable. Well, I stand corrected. I've seen it with my own eyes.
