Looking at the comments here, and I think the negative thoughts and predictions are the ones that will be correct.
In spite of a record commons majority the current government seem paralysed, and hugely unpopular.
None of the 'senior team' will want to promote any railway investment beyond 'lip service'. East West rail beyond Bedford may get a 'study' but as for meaningful construction, there will nothing promised. HS2 will be a topic which all the politicians will avoid. Any extension to the existing scope will not happen, same with NPR, its dead, but no one want to actually admit it.
ToCs will continue to be nationalised, but progress to 'one railway' will be painfully slow, with issues like ticketing complexity being shelved as being too expensive, so the current compartmentalised system will continue.
I also predict that the DfT aka government will try and limit Open access operators going forwards. It goes against their view of the world. Nothing will be done to address the problems which have lead to the current issues facing the railways.
