Napa Valley Wine Train There's a ban on traditional billboards throughout much of California's scenic wine country. So the Wine Train staff got creative and painted a maintenance of the way boxcar to use for outdoor advertising. This car has no road number or end numbers (the real car doesn't have them). Brown Atlas 40 ft boxcar with white and black printing. Micro-Trains® trucks and Magne-Matic® couplers. Part Number "Napa Valley Wine Train" $19.95 each
