The 365 is surely the least important member of the "Networker/Turbo" family anyway, so would be an odd choice to preserve.
Depends how one looks at it. They’re generally regarded as having been the best of the Networker/Turbo family, which counts in their favour. Then there’s the claim to fame that 365541 can probably be regarded as the final BR train, as well as the final unit built at York.
I think they have as much claim as anything else. It wouldn’t go amiss to put one back to the original interior. Most of the “dumbing down” changes could be fairly easily undone.
I hope some get saved. It hasn’t helped that they have disappeared rather prematurely, so won’t really have been in anyone’s thoughts. This conversation should have been happening 10-20 years in the future.
I’d have a car in my garden if only I could get it in.
