What he did offer was money to make the system compatible in London. As Slough is outside London it never would have worked at Slough even if they had taken the money. Oyster▸ is a London system and does not work outside !!!!
Call me a cynic, but I think this is an intentional stunt on Livingstones behalf. What he is trying to do is keep positioning himself as public transport's only possible saviour, but mainly to keep one major issue bubbling away, which is this...
Whenever Oyster
PAYG▸ is finally rolled out with all the London
TOCs▸ , there will still be all these 'edge cases' where it can't be used, that are the homes of millions of London commuters. Think of Gerrards Cross, High Wycombe, Slough, Windsor, Weybridge, Epsom etc, and that is just to the west...
But you can't just keep expanding the zonal area across the country concentric to London, at some stage there has to be a stop, and then an interface with other zonal fare systems. The big political question is where do those natural boundaries lie. In any case 'orbital zones' aren't necessarily correct for everywhere else, but work for London because they've realised the vast majority of tube journeys are radial. Buses are different with
TfL» , you pay per journey.
Of course if places such as Slough could be sucked into Greater London, just to make fare simplification possible, they'd bring all the relevant local authority's income into the GLA's accounts, where it could be spent in Ken's heartland...
