Lilloaf - mate, you really need to have a think about everything you state is wrong with Northern AND the (deserved) derision that has enticed from other members of this forum. When you have mulled that over, if you still think Northern should hire in HST's to travel from Carlisle to Nottingham, I would love to hear why you think this is a good idea and how exactly it would improve the service Northern already provide.
The simple fact of the matter is this. Northern have channelled what resources they have, made their usage more efficient, improved performance and punctuality, increased services, increased capacity, improved their aging and maligned (142) stock immensly and hired in extra stock where needed, formed a good relationship with customers in which their views are, not only listened to, but acted upon and as a result have overseen a massive increase in Patronage and were awarded Public Transport Operator Of The Year 2007. Not only that, but they do not even have the catastrophic problems with the Class 180s that everyone else seems to have.
I cannot think of anything else that Northern can do to improve other than altering some timetables that are currently a bit weak in the Manchester area.
No one on this thread has had a go at AXC. They are also doing a very good job. Under the Virgin days, the delays they suffered were unbelievable. That has been improved no end. As has the quality of service. As has the ambience on board. But, honestly, to attempt to compare Northern in a negative way next to AXC? And with some of the wafer thin arguments you make? You are fighting a battle that you lost even before the very first letter of your very first comment.
As an aside, isn't it interesting that the interior of a train (class 333 specifically) is able to be kept to a very good standard despite being in service nearly 10 years when they are exclusively sent to the more affluent areas of the network?! Not trying to start a gang war or anything, just making a point....
