Not to be a snarker or anything, but why is it unfortunate to replace 50 year old and beat up trains?
What Blackbuck said
I used to have an hour long journey home with an almost guaranteed seat every time, but the new S Stock have longitudinal seating which significantly reduces the capacity of seated passengers, resulting in having to stand most of the time. The old trains also have a bit more character, despite being a bit more bumpy at speed. I hope they find another operator once LU is done with them - I heard rumours they made be used around Leeds.
