Thanks, Nasaroc. But I must say that, to the extent that I understand Southern's paragraph 20.4, it doesn't sound to me like 'arguing strongly' in favour of retaining our CX service. They say that they'd support it 'all else being equal', but then seem to concede that their rivals (I assume) for CX slots, Southeastern, have 'real concerns' about their own capacity. They go on to make wistful suggestions about what might happen 'if there was a case [!] for Southern taking priority over Southeastern.' All a bit feeble, isn't it?

Do you know whether there is an reasoned explanation anywhere of why in the event Network Rail decided against us?
