I had no idea this was ever done. Has anyone ever seen one of these in person? Automobiles shipped nose down. http://www.amusingplanet.com/2012/12/vert-pac-unusual-way-to-transport.html
There was a whole discussion about these when ExactRail released HO models of these cars; http://www.frisco.org/shipit/index.php?threads/new-ho-exactrail-vert-a-pac-autorack.4325/#post-29779 I had a 1971 Vega that had been transported by Verta-a-Pac railcar. The vehicle was designed to be transported nose-down.
