Here are some thoughts and question on what happens now:
1) Will this finally mean renationalisation? Answer: no, this is Grayling we're talking about. The Government won't take it back into state ownership even temporarily if it could work towards building a greater case for nationalisation, so...
2) We're probably looking at another tendering process. So who will be bidding? Virgin, again, in a majority stake? Stagecoach on their own, seeking to start afresh? I imagine that First will properly make their move now. Perhaps Arriva will take hold of the franchise - in which case, integration with CrossCountry would be interesting - or maybe an entirely new franchisee? Or even someone mad like Abellio?
