If this all goes well I really do hope deals can be done to extend the application of the MKIVs. I would love to see them on more of the North/South wales services and:
Manchester - Cardiff
Liverpool - Holyhead
Liverpool - Nottingham (although I accept 185s much more likely but the MKIV environment is much nicer for intercity route like this).
Increasingly it feels like there might be options to boost capacity in the north and Wales without any further new orders, if the right deals can be struck with the leasing companies and the Government is willing to repay a little of the hopefully not misguided trust that has just been placed in it. Time will tell if anybody in Gov/the DfT really is capable of that level of rather obvious imagination.
