I've already got a whole thread dedicated to this but my Lego Liner 100% fits here:
It's a heavily modified Lego KT404-1 Small Locomotive with Tender set from the early 2000s that's currently outfitted with an MTH trolley motor, but by this weekend will hopefully have a Lionel Junction 0-4-0's frame and guts in it.
It's also a bit different but I purchased a Cobi (lego lookalike) kit of a German Panzer 3 tank which conveniently enough is 1:48th scale. As for why and how a German panzer found its way onto an American freight train, if the US Navy can get the warship "Prinz Eugen" as war loot, the US Army can have a couple tanks, as a treat.
