Thanks for the great video Chris!
I have 20 89' Lionel Autoracks and I think 10 Lionel 86' Boxcars. They certainly make for a long train and even make the biggest of the Austin Tinplate Trackers layouts seem small. Below is a video of my autorack train.
My dad and I store a lot our stuff Train Boxes Plus boxes, baseball card boxes, paper, and legal boxes. You can get a lot on those and they stack easily. Helps make transporting them to run on on the Austin Tinplate Trackers layout as well.
