Im in two minds here.
Ive mentioned before that I am in favour of rationalisation. By that, I suggest that the current franchises are conglomerated into super-franchises, much like the current Greater Western franchise that fGW hold. I would like to see six super franchises created;
-Scottish and Borders (although technically already in existence) to include current Scotrail services, SPT and cross-border runs to Newcastle and Carlisle.
-Northern (much like the current franchise) which covers the north of England, and much of the EMT/London Midland long distance routes that extend into that area, as well as the TPE routes.
-Southern, to be much like the ex-NSE area, which includes the South Central, Southeastern, new Thameslink, all SWT routes excluding the runs to west Country, FCC, the metro services and mid-distance services of NXEA, the WCML services to Birmingham, the Chiltern services to Aylesbury/Princes Risborough and the Thames Valley services from the fGW.
-Wales and West, covering surprisingly all services in Wales to the midlands, all suburban services in the West Country, and the long-distance SWT services.
-Midlands, covering everything else left over, including the EMT connect routes, the West Midlands PTE routes etc.
-Intercity, covering all IC routes including CrossCountry.
Now, I dont think that would work particularly efficiently, as it only compounds the problem that we are currently facing, which is DfT getting in the way of what private companies want to do make money by making improvements. So instead I propose
National Rail one complete network run by one company (preferably Govia looking at the big 4 of today), which includes the areas mentioned above as distinct regions, with the exception of Cross-Country which will remain a separate identity, and include the Eurostar services out of St Pancras, and services from Leeds, Manchester, Edinburgh, Glasgow, Newcastle and Birmingham.
On top of that, the infrastructure remains in private hands, such as we have now, and the entire network replaced over a period of x years (which I am aware will take ages). This includes a complete replacement of ex-BREL rolling stock, and the continuation of the ICE-P. Give the project to Bombardier-Siemens consortium, and then approach Siemens to build a new generation of Desiros to replace all old AC electrics such as the 313s etc, and Bombardier for new Meridians to work express Scottish routes, west country routes and new Turbostars to replace the 14x and 15x fleet. The 16x fleet routes will be electrified, as will most of the network where possible.
To aid extra capacity in the short run, build some new class 344 (AC versions of their DC sisters), replace the class 90s and Mk3 on NXEA IC routes, rewire them to work with skips, and chuck em into Cross-Country, cascading some Voyagers to work the Chiltern route expresses, freeing up Turbostars to head North and add much needed capacity. In addition, give TPE route the 180s for Scotland workings, and use the ECML north of Newcastle in addition, give the 170s to the Northern area.
Would never happen I know, but still, I dream on of an efficient British rail network.
