During the late 1960s GM was looking to reduce shipping cost on their Chevrolet Vega that had to be moved to dealerships across the country via rail roads.

The maximum a boxcar would hold was 15, so General Motors and the Pacific Southern Railroad decided to design their own vertical packaging boxcars called Vert-A-Pac that could vertically carry up to 30 cars at a time, reducing transport charges per vehicle by 40%.

The Chevrolet Vegas were topped up with fluids so that they could be unloaded and ready to drive to the dealerships. To prevent fluids from leaking, Vega engineers had created a special engine oil baffle that stopped oil from entering the cylinders. Batteries had filler caps located higher to prevent acid spills and the the carburettor float bowl had a special tube that would drain the gasoline into the vapour canister during shipping.
