Railroads now started to again become a major shipper of
finished automobiles. In 1965, for example, the New York Central
hauled 1.1 million new automobiles, and added new freight
schedules such as train ML-12, a daily auto rack train traveling
from midwestern assembly plants to eastern terminals. This
train regularly rated six new General Electric U25b locomotives
and was frequently two miles long, consisting entirely of
multi-level cars. During that year the Pennsylvania Railroad
hauled a half-million new automobiles.
The auto rack cars helped breath new life back into the railroads,
but like its ancestor, the auto boxcar, the rack car had both
advantages and disadvantages. The new open cars were able
to carry a larger load, and they were a colorful sight to
train watchers. In those days, one could see the fresh, factory
made autos as they traveled to the dealers but of course not
all train watchers were friendly when these freight cars went
into service. Because the cargo was exposed, the rack cars
became prime targets for vandals. In addition, the greater
height of the cars required clearance modifications, and not
all rail routes could be used. Automobiles carried on the
exposed upper deck also suffered damage from exhaust soot
if coupled directly behind the locomotives, and it was found
on some railroads in winter climates that water seepage from
their tunnel ceilings formed icicles, which were damaging
automobiles. Some railroads constructed a steel framework
of pipes on a flatcar which they would periodically run over
their lines to clear away the icicles, while Southern Pacific
mounted a hinged system of piping on the roof of some locomotives
to do likewise.
The large number of exposed automobiles now appearing on
the railroads became a tempting target for vandals, and by
1970 the cost of claims to the railroads for shipping damages
was beginning to reach its peak. Vandals were positioning
themselves track side to sabotage the trains or staking out
on overpasses. Parts were found to be stolen from automobiles
during shipment. Automobile windows were also being damaged
by thrown objects. In response, railroad and local police
and the FBI began "riding shotgun" on the auto rack trains.
To combat these problems, many rack cars began receiving enclosed
side panels that helped reduce damage from foreign objects
and kept the product somewhat hidden, but it introduced another
problem - the trespasser. The hobo, vagrant or illegal alien
usually found his place in an empty boxcar, but the enclosed
auto rack cars were an open invitation to these "free riders."
It was a lot easier to stow away in a new automobile, plus
it was a much more comfortable ride. I am sure everyone appreciates
the "new car smell" when buying a brand new vehicle. Imagine
what that automobile would smell like if a hobo slept in the
back seat for a week or more!
During the 1970s, major steps were taken to modify the auto
rack car. Goals were to provide protection from the elements
as well as to reduce vandalism and theft. One measure taken
was the installation of side screens. It reduced vandalism
but did not stop theft. The material used was a wire mesh
very similar to chicken wire; a good example is the rail cars
used by the Canadian railroads. Some of these cars with wire
mesh are still in use today. In the United States, the rack
cars took on a "paneled" look, with the car sides now covered
with wire mesh, fiberglass or a corrugated metal screen. These
"paneled" auto rack cars were a common sight on the nation's
freight trains.
It is often said that what goes around comes around. When
automobiles first traveled by rail, they went in boxcars -
a fully-enclosed environment. The 89-foot auto racks that
travel on today's railroads have evolved into fully-enclosed
cars. The side panels and roof on these cars provide full
protection from the elements and vandalism, and are still
available in bi-level and tri-level styles. Today, the bi-level
models transport trucks, vans, sport-utility and other high
vehicles while the tri-levels handle sedans and compact automobiles.
When the auto rack first came into favor by the railroads,
many carbuilders played a role in the construction of the
rack assembly. Major builders in the beginning were Whitehead
& Kales (also a large auto transporter truck trailer builder)
and Portec's Paragon. They were soon followed by Pullman Manufacturing,
National Steel Car (licensed to build W&K products in Canada),
and Thrall. Manufacturing today is handled exclusively by
Thrall.
How is automobile traffic handled? Originally, the rack cars
were assigned to the major automotive assembly plants. Operation
was quite simple - the cars left loaded and returned empty
to the plants. An empty car makes no money for the railroad
so in 1979, to reduce empty miles, cars assigned to General
Motors moving in certain lanes were reloaded at assembly plants
close to their unloading points. Over time, all the automakers
began to follow this practice.
Today, auto rack cars are assigned to equipment pools. Just
because a rail car has a certain railroad herald on it does
not mean that it is assigned to that owner. Automakers of
today have undergone consolidations over the years, and their
vehicles are traveling longer distances. The shipment of new
vehicles by rail has become more competitive because some
foreign auto makers have built plants in the United States.
Loaded rack cars with American autos move west, while the
imports move east from the West Coast.

The North American auto rack car fleet is managed today by
Trailer Train. Approximately 59,000 cars are managed by TTX,
while the remaining 6,000 are owned by individual railroads.
Class I lines handle most of the traffic, while regional railroads
see very little. Throughout history, there have been some
short-lived experiments in the shipment of automobiles. The
New York Central had some of its Flexi-Van container boxes
constructed to carry automobiles. A specialized railroad boxcar
enclosure was designed in the early 1970s to transport the
Chevrolet Vega compact automobile. The Vert-A-Pak car had
sides that would hinge downward, forming a ramp. The autos
were parked on this ramp and securely tied down, and the sides
were flipped upward to close the car, with the Vega traveling
vertically on its nose. Needless to say, Chevrolet had to
carefully design the Vega so that fuel, lubricants, battery
acid, etc., did not leak out in this shipping position. Another
experiment was the Stac-Pac. This car consisted of a low-deck
flatcar with special straddle loaders. Automobiles of any
size were carried three deep in a separate enclosed box. Both
Vert-A-Pac and Stac-Pac were short-lived because they were
labor intensive and took up too much real estate.
To provide even greater productivity, one of the recently
introduced models to handle automobile traffic is the articulated
auto rack car, the result of a joint effort between the rail
industry and automakers. These cars are simply two car bodies
riding on a common center truck, and are designed to ship
any type of automobile. Loading and unloading is the same
as with conventional 89-foot cars, but the articulated cars
carry almost twice the load. Side panels of these cars are
solid steel. To match the clearances of conventional single
auto rack cars, each section of the articulated car is 68
feet in length, with an overall car length of 140 feet. The
Auto-Max, built by Greenbrier, is currently owned by BNSF,
CSX, Canadian Pacific, Ferromex, and Kansas City Southern.
New automobiles are still a major source of revenue for today's
railroads, primarily the Class I lines. Merchandise freight
trains are frequently seen with auto rack cars in the consist,
and solid trainsets of rack cars are still operated. Probably
the key player today is Norfolk Southern. Its mainline from
Detroit to St. Louis and Kansas City by way of Decatur, Ill.
funnels automotive traffic from the Motor City to other railroads.
The former Wabash line currently serves nine on-line auto
plants, and in 1994 more than half of NS automotive traffic
rolled over this portion of the system.
Just to get an idea of how many new autos go by rail these
days, let us take a look at the Melvindale Auto Distribution
Facility. This loading ramp on Norfolk Southern takes in vehicles
from all the Chrysler plants in Michigan and nearby Canada,
as well as Ford Mustangs. In 1994, Melvindale handled 29,922
carloads or 345,263 automobiles. In June 1995, 115 to 150
auto racks were loaded per day. The ramp was initially constructed
by the Wabash in 1959-1960, and expanded to 13 tracks in 1994
with a total loading capacity of 96 rack cars at a time.
The popularity of auto rack cars is not restricted to the
freight railroad industry. One of Amtrak's most popular services
is its Auto-Train, operated daily on a nonstop schedule between
Lorton, Va., near Washington, and central Florida. Based upon
the initial success of a 1970s private operator, this train
carries its passengers in the latest Superliner equipment
while the customer's automobile follows in its auto rack toward
the rear of the train. In fact, it is required that passengers
have an automobile to transport before Amtrak will sell a
ticket on the Auto-Train. The loading and handling of each
car is similar to that practiced by the freight railroads.
The transportation of new automobiles is a major traffic
segment for America's railroads and may be for many years
to come. It will be interesting to see what new developments
are ahead in the future.
