Time to trust our politicians perhaps? 
A valid question B.
In the light of First Group's rather financially robust bid to run the West Coast services for the next few years, the displacement of the current operator (Virgin Trains) as a result of its acceptance and the (obvious) hope by the Department for Transport that things will not go teats up (à la East Coast line), I think it quite reasonable to ask whether or not it is sensible to trust the government’s strategic view on all matters of critical infrastructure – particularly in these matters of transport.
This government (and those of recent times) appears to have fallen victim, with disappointing regularity, to those in the commercial sector who promise much to secure a contract but deliver little when the anticipated profit margin can’t be achieved without a subsequent (and obvious) reduction in costs.
As a result, the inevitable diminution of service standards for those unfortunate people who have no alternative but to use them, the continued development of (and investment in) the core purpose of the business and, of course, the reduction in value for money for the taxpayers who must fund these ventures (at the behest of confused government) seems to be blithely accepted in the knowledge that little or no sanction will ever be levied against those who are instrumental in creating such fiascos in the first place.
