Mine gets its first run tomorrow, hopefully.
I need to make a few new small cars to pull behind it and a small caboose.
I have just what you need!
It even comes with a choice of roof.
I built it while in lock-down, intending it for my feldbahn - but that got an even smaller van. This one is/was an Ozark Clear Creek 10' kit. (PM me if you want it.)
