Let's please put this to rest.
Myself and others have pointed out that the 317s are not skips that are unfit for purpose and need to be scrapped, but nobody has said they're in good condition (poor maintenance, shortage of parts etc) and don't need work.
I've said, as others have, that a proper refurbishment, new traction and so on could give these another 10-15 years. And people seem happy with what LO has done on the 315s and 317s, which is minimal, so further proof that some TLC can make even the current stock look more loved.
I believe that one way or another, the ROSCOs will update the fleet and if they don't stay, they'll move on. And by being overhauled, the ROSCO will be able to still lease for good money and will be happy.
Some might need to be scrapped, but there's a LOT of trains there. I am sure they can mix and match as necessary to build a standardised fleet of really good, reliable, comfortable and modern looking trains.
So, nobody has said AGA users deserve the trains to be run into the ground as is happening - but they're NOT fit for scrap just yet, or certainly not most of them. The 321s are just the same as the 317s, and also have plenty of life in them SOMEWHERE.
Who knows what will happen with the 315s or even the 313s. Most likely for scrap, but you never know.
