I thought he was making a wry joke re "sorting in the back of vans" but maybe he (and possibly yourself) really don't understand the AI set-up?I can't see how it's possible to process mail on the roads. As Axeman pointed out, the Law prevents anyone being in the back of a Lorry or Van on the move. So the only way to do that, would be on the Railways. Wchich is why he menioned the TPO as an example.
It's "off-line" processing; the images can be coded at the MDECs while the letter is physically being moved in Yorks by road.
At the hub or destination it's refed into the mech for it's route code (bottom line of orange ink) to be printed, and to be sorted to the relevant box. That's the basics.
.Axeman has already given one example of what can happen. We need some spare capacity, within practical traveling distance. I know that redundant backups would be impractical, due to the cost
Fires, plane crashes etc are once in a life-time occurrences, and don't think you'll find many, if any, firms would allow for those events when planning for the future.
They wouldn't last appreciably longer, and as most faults and breakdowns occur from so-called "cold start ups" there wouldn't be any real gain.But machines which aren't running at full capacity, will last longer (as they aren't under as much strain) and can take some of the extra load, if something goes wrong.
.As I said earlier: You've obviously put a lot of thought into this, and are making some good points. But I'm still not convinced that it's a wise course of action
Actually Andy, I haven't put any thought into it, it's just the accepted way in industry, proven over decades. As to being a wise course of action, only time will tell, but RM do have a history of making decisions, the decision-makers moving on after two years and those left behind having to pick up the pieces and rebuild....
