Another point to consider, when leaving trains to the family is passing on the knowledge of how to operate and care for them. That's if they want the trains. Even if they don't documenting everything you have will be helpful to the next owner. Ready to run trains are fairly simple to document with pictures and instructions. Include your own hand written notes about the trains and what quirks they may have.
My large scale trains are another issue. I have converted every one of them to battery power with radio control. Fortunately, the company I use for the R/C components is excellent at tech help. However, I feel that instructions, clear photographs and videos would go a long way in helping the next owners to understand the trains and not get frustrated.
Now, my next task will be to actually get started on my documentation.
