Received an email with some Thameslink Programme blurb today, but was a bit confused by the following regarding the new Blackfriars entrance on the South Bank due to open Dec 5th: This raises a few questions: What does it mean by 'ticket holders'? Obviously anyone with an Oyster season that includes zone 1 will be let through barriers on the north and south sides fine, but what other ticket holders will be allowed through (any seasons to London Terminals/Thameslink)? Those Oyster PAYG conditions also seem odd. I can understand the "you must catch a train from Blackfriars with... London Underground" clause if one, say, entered the station from the South Bank side to access the tube on the north. But "you must catch a train from Blackfriars with ... National Rail"? Would the South bank barriers not let through a PAYG Oyster holder who had touched in on the north side? Finally, what do penalty fares have to do with all this? Presumably a PAYG Oyster user crossing the station bridge would just pay the zone 1 Oyster single fare (or possibly the max Oyster fare if they forgot to touch out)?
