It's a shame you couldn't find any Superbirds for that layout. They'd be perfect.
;D
HA! I actually used to have a toy that would be perfect for that.Looks good. You will need to set up some little remote control launch mechanism so that when you have visitors viewing the layout, you can shoot the Dukes Charger over the passing train.
Its looking real good. I like the desert scenery and the truck looks right at home...lol. Keep them coming.
