...they are selling an extra 200 tickets a day on the Sydenham Town forum video. That represents an increase in sales of around 2%...
Quite a big difference in the figures being quoted - is there a source for any of these that can be checked?
I do think there are people out there who have been buying a 1-2 Travelcard and rely on Southern's "open-gate" honesty policy and the fact that there were barriers only at L Bridge and at best sporadic checking at each station. But I also think that the extra revenue will become pure profit for Southern after the running costs of the gates are taken out (i.e. we won't see any further station improvements...)
