At 62 I'm finally working on the larger (for me) layout that should be 6 x 12 when finished. My plan is 3 tables each 6 x 4. They should fit in the back of standard pickup truck when we downsize again. Now I have everything in a two car insulated and climate controlled garage.
I'm still working, going to dialysis three times a week and waiting on a kidney transplant. In the meantime I've sold all of my baseball cards, comic books and video games. I still have a few other collections that will go first. That creates a slush fund for the railroad.
I have a lot of train sets in the original boxes. They take up a lot of storage space. Plus another 100 or so freight and passenger cars. That may be a problem later on.
My wife made it a point to get me a new train set every year for Christmas. I finally had to convince her that I had enough trains, imagine that?
