Tube bosses recently were forced to destroy nearly half a million London Underground maps after they accidentally printed them with a tiny error. Transport for London noticed the mistake part of the way through the printing process – by which time 474,280 of the maps had been produced carrying the mistake – Morden, the last stop on the Northern line – was incorrectly placed in the tram zone rather than zone four.
Eek mistakes can and do happen but make every effort to make sure what we print is correct that’s why you will always get a proof and be asked to double check all information.
