| Remember the Chevy Vega? This is how some were shipped. |
Until the early 1960s, automobiles moved by rail were carried in boxcars. These were 50 feet
long with double-wide doors. Inside was room for four full-sized sedans on a two-tier rack -
two raised up off the floor on a steel rack and two others tucked in underneath them. This
protected the cars during transport but wasn’t very efficient, as the weight of four vehicles
was far less than the maximum weight a boxcar that size could carry. When 85-foot and
89-foot flatcars came into service, it was possible to pack a total of fifteen automobiles in
one car on tri-level auto racks. But it still didn’t approach the maximum allowable weight
for each flatcar.

When Chevrolet started designing Vega during the late 1960s, one of the main objectives
was to keep the cost of the car down around $2,000 in circa-1970 dollars. At the time,
the freight charge for moving a loaded railroad car from the Lordstown, OH assembly
plant to the Pacific coast - the longest distance cars produced at Lordstown would need
to travel - was around $4,800. Since the Vega was a subcompact, it was possible to
squeeze three more cars on a railroad car for a total of eighteen, instead of the usual
fifteen. But that still worked out to around $300 per car â€" a substantial surcharge for
a $2000 car. If only Chevrolet could get more Vegas on a railroad car, the cost per
unit of hauling them would go down.
The engineers at GM and Southern Pacific Railroad came up with a clever solution.
Instead of loading the cars horizontally, the Vegas were to be placed vertically on a
specially designed auto-rack called the Vert-A-Pac. Within the same volume of an
89-foot flatcar, the Vert-A-Pac system could hold as many as 30 automobiles instead
of 18.
Chevrolet's goal was to deliver Vegas topped with fluids and ready to drive to the
dealership. In order to be able to travel nose-down without leaking fluids all over
the railroad, Vega engineers had to design a special engine oil baffle to prevent oil
from entering the No. 1 cylinder. Batteries had filler caps located high up on the
rear edge of the case to prevent acid spilling, the carburetor float bowl had a special
tube that drained gasoline into the vapor canister during shipment, and the wind-
shield washer bottle stood at a 45 degree angle. Plastic spacers were wedged in
beside the powertrain to prevent damage to engine and transmission mounts.
The wedges were removed when cars were unloaded.
The Vega was hugely popular when it was introduced in 1970, however it quickly
earned a reputation for unreliability, rust and terrible engine durability. When the
Vega was discontinued in 1977, the Vert-A-Pac cars had to be retired as they were
too specialized to be used with anything else. The Vert-A-Pac racks were scrapped,
and the underlying flatcars went on to other uses.
