Well If c2c (or LTS) hadn't got rid of 312's there wouldnt have been the problem of air-bourne diseases, as they would all be blown out of the window and replaced with fresh-air, but in these air-conditioned capsules, they call trains, no real fresh air can circulate, the air becomes diseased, stagnent and hot (if the air con is off / broken) and you have a cold / flu infested train! So, c2c, either: fit opening windows to you Electros**s or bring back 312's!!! - as if!!
Anyway, I hope all the Essex people here enjoy your no-sneeze/ cough zones!! God imagine enforcing the rules though!! are c2c hiring a special branch of the BTP - "Cough Police!?!"
