This is a problem in the entire collection hobby, whether it is railroad cars, classic cars, truck, etc. They reach an end of their life someday. Sadly in our hobby, these are huge pieces that require huge amounts of money to move so they often wind up getting scrapped. And yes, while there are those who wish they could have been saved, and there are those who wanted them, the funds to keep them from scrap just isn't there in these tough economic times.
You can learn just as much from what is not said as you can from how much is said.
