The window/seat alignment has been sorted out.
No, it hasn't, there are plenty of misaligned seats, it just isn't as obvious as unlike the 195 it's not all tables. The 196 does sort it out, though.
The 196s have “sorted it out” by making the windows smaller and ramming in an extra row of seats, though, so there’s less light and less leg room. Not sure why that’s considered a good thing.
The windows on 195s and 197s are reasonably sized for their seating – as can be seen in the end sections of each carriage, where the 6 rows of seats and windows are aligned well.
The difference is that while a 196 has 10 rows in the central section (i.e. between the doors), a 197 has 9 rows and a 195 has 7 (plus tip up seats at either end for more circulation space around the doors).
You just cannot have an odd number of rows of seating aligned perfectly, no matter what size windows you have. (Well, unless one window is half the width of the others, which would look ridiculous.)
Seems to me that Northern and TfW have made perfectly acceptable choices based on the intended use. The seat alignment is fine. I’d much, much, much rather have more leg room (that is, more comfort and ease of use) than worry about a pillar being slightly out of line, and I’d guess most passengers would say the same.
(I’ve never understood the obsession with seat alignment anyway, I often head straight for a seat without a window if I can – easier to work on a laptop without the sunlight, and easier to sleep with your head on a wall instead of the glass!)
