I guess it makes sense. The best of a bad fleet + all based in one depot + slightly more capacity than 8 x 769s. It will be interesting to see if 153s will be kept longer too. Still looking like a batch of 142s will leave Northern next month, which is a good thing!
I don't feel it is such a good thing. During the hot weather, I have found the 142s the most comfortable units to travel on sat on the bench seats near the doors with a breeze coming through them. Modern units have AC that does not always work properly such as on the 158s.
Yesterday, I travelled on one of the new Class 195s between Manchester Piccadilly and Wigan NW. I am very disappointed with them; the doors closed themselves when people were trying to board, a lot of people had luggage and the gangways were not wide enough, the toilet was broken. Due to the narrow gangways, it was very stressful trying to get past people to get off. All recent rolling stock seems to be built narrower than the full rail width of 2.83m and narrow gangways are a problem. This applies to 185s and 350s as well. Gave me a Pacer any day.
You can still have 23m length carriages with a width of 2.8m.
