Before we get into the nitty gritty, a little background which might help to explain why Epsom took so long. Epsom station is managed by Southern, part of Govia Thameslink Railway (GTR). Trains are operated by Southern and South Western Railway (SWR), and SWR are designated as the lead operator so they set the majority of the fares from Epsom. One of GTR’s franchise commitments with the DfT was to enable Oyster PAYG at Epsom. To do this they had to provide the infrastructure at the station, liaise with SWR and TfL over what fares to charge and how these could be integrated into the existing Oyster system, and run the whole thing past the DfT for a final sign-off. Anyone with any experience of big companies liaising over projects will realise that this was not an easy task.
With that out of the way, now we come to what’s actually been agreed.
