"new" Bachmann Doodlebug

I found this one used, took it home, and mounted a decoder to its undercarriage. You can't see it here. I need to go back still and blacken the wires where they are visible and build some sort of view shield around the decoder, or make it look like it's supposed to be there (some sort of tank or something like that). These are pretty nice little things for running at the layout when you don't want to mess with a bunch of cars.
