ThanksIt's certainly possible, if you're willing to stretch your "distant future" a little further.
The 195s are 15 years younger than the 185s, 15-20 years younger than the 170s, and younger still than all the Sprinters, so they will probably remain in service after they're all gone. (The 150s at least will probably be replaced in the next franchise.)
The question then will be "what else would suit the line"? Assuming that electrification doesn't reach this line, it'll be a choice between the 195s and any future diesel/bi-mode unit that hasn't been built yet.
But to see them on the Settle-Carlisle in a year's time? I don't think that's in the current franchise's plan at all.
I just gave those dates as examples. I myself see 195s on that line being a likely possibility at the end of the franchise, I myself don't really see it happening next year either
