This is ambiguous or worse. The correct name for Kensington (Olympia) is Kensington (Olympia) KPA and not 'London, Kensington (Olympia)'.This applies to all trainstravelling towards London, Kensington
(Olympia) or Brighton, and trains leaving
London, Kensington (Olympia) or
Brighton between 27 July - 9 Sept 2012.
Hence I read it that non-folders are banned for all Southern trains arriving/leaving 'London' as well as Olympia. I hope I'm wrong and no station staff read it that way. Otherwise your diversionary tactics could fail. Alternatively why don't we just declare this ride 'D-(itchling) Day for Brommies' and have done with it?
