This has a lot in its favour. IF a motivation is to be able to increase the 'feel good factor' and to return another labour government at the next General Election then 'wins' must be not just promised but delivered within 4 years (well within if lost by-elections and local government elections are to be avoided). So an assessment of how many (and which) constituencies could and must be 'saved' may be revealing and pertinent. The relevance of XC to this is in the name. Could longer trains be introduced quickly using existing unutilised stock, and at little (or no?) extra cost.Sorting XC capacity is the obvious one. Its overcrowding is well known, and the TOC spreads across the country (aside from Northern Ireland).
Fare reductions risk increasing overcrowding.
I like the 'quick win' of Network North West, Network North East etc, but for the haggling over boundaries and the time and hassle to get it up-and-running. easy to 'announce' but that's an empty 'promise'.
How about 'get Great British Railways done'!
In passing, are Reliabity and Delay stats still recorded and published? Could they be made to relate to 'fining' of operators for poor performance- Offtrack, akin to but more effective than Ofwat, etc? Passenger Charter??
