I am not very happy with the service Northern provide either, I use them regularly as I live in their area (I have many gripes), however some of the problems with their service is not all down to them, for example they inherited the pacers and sprinters of which you speak, on the other side of the coin I believe they could have made more of an effort to get better trains.
But rather than condemning them I would rather try to encourage them to improve their services.
If you compare Northern with other rail franchises, I suppose they do not come out well, but not the worst in my opinion. All the passenger rail companies have faults, some more, some less.
In my area we have TPX who I believe do provide a better service, Virgin (ditto), Cross Country (similar), Arriva Wales are not too bad, but the worst in my opinion is EMT, not for their trains (mostly 158's which are ok), but for their customer service which is rather poor from my experiences travelling with them, how they got passenger train company of the year eludes me:roll:.
Further afield I have not travelled enough on other companies services in which to formulate a balanced opinion, but from what I have experienced I enjoyed travelling on SWT and Scotrail, London Midland left something to desire, every time I travelled on locals in the West Midlands the trains were always rather dirty, same for the Cross Country midlands services, down to the local staff I suppose?
So for me anything to improve our rail services is welcome news, even with Northern, and I would sooner travel on trains around the North West (even with Northern) than drive, especially now in winter when the roads are a complete nightmare!
Edit :- I have just seen (from a post on a different thread in this section of the forum) that Northern 144's picked up the most reliable pacer in the country:roll:
