Much has been made on various threads about the change from traditional 'closed' stations to 'open' stations, and the more recent reintroduction of ticket barriers at formerly-open stations.
Was the only difference between open and closed stations the presence (or otherwise) of manual ticket gates? What led to the decision to make stations 'open', and when was it done?
