As a passenger (nowadays) I would say none, and I bet most other customers would give the same answer. What is your answer to the question?
I too am not interested in classes of trains, although I do look forward to a trans-Pennine journey on one of these fabled trains that doesn't have a big diesel engine thrashing away under every coach. In fact, I would like to go on something (anything) more than 3 cars long that I can be sure of getting into at Leeds.
I have no idea when it might actually come to pass though. We were promised loco-hauled trains a couple of years ago, but TPE decided that it was beneath their dignity to honour a franchise commitment. I have yet to see a train longer than 3 cars (other than one flashing past in the opposite direction - which might well have been running empty) and am dreading coming home over the Pennines on 23rd Dec. I can go out via the Bentham line, but will probably give in and try the "direct route" home.
I can’t instantly think of any trains running on the network that have not caused any delay minutes. Can you?
I’m flattered that you’ve taken my list of cancellations as definitive. I must point out one final time that it’s simply what’s publicly available, rather than industry knowledge, and the reality is likely to be even better than what I’ve listed.
Don’t just take my word though, you’ve now had two people with far better access to information than I do give you some figures. You’ve now moved to the notion that anything less than 100% reliability for a new train is not acceptable. You asked me what I think is acceptable and I’d say the current performance, especially for a new train, is excellent.
On several occasions recently I’ve had a master shot lined up of the locomotive only for
@D6700 to bound from the train and ruin it, so yes, they do use the trains
As
@tpjm has mentioned, I myself am using and enjoying the trains, I’ll readily admit perhaps just a little too much
On a more serious note, I was fortunate to travel on the very first Nova 3 service. There were several people present who had clearly been involved with the project and what shone through was the enormous pride that they take in the train. It’s the same story when having a quick chat with drivers, conductors or catering hosts. In addition, I’ve yet to travel on a Nova 3 (or Nova 1) without hearing positive comments from passengers.
I wish you a very pleasant journey over the Pennines and hope that you get to sample one of the Nova trains.
