This is a self-contained train loop I created this past winter on MILs plates to take to various train shows around Colorado. It features a motorized dog playing fetch, LED lighting, and a working 9v proto-train. There are some miners excavating trans-pink ore.
If you are local to Colorado, you can check it out at the Boulder Bricks & Minifigs store for the next few months.
Thanks to Matt Hudson for the photography!
