AUTO TRANSPORTING PASSENGER TRAIN CAR BACKGROUND OF THE INVENTION Long distance travel by automobile is viewed as a problem not only by travelers but also those concerned with public safety and efficient use of our dwindling natural resources. A major drawback to the use of mass transit systems as a substitute in long distance travel is that the traveler cannot take his automobile along for use at the other end of the trip. This desire to take the auto along is important to a sufficient number of people to render commercially successful at the present time at least one rail operation that offers private auto trans port.

One key to any future large-scale success of the autocarrying train is an effective design for the train car. In this respect, several factors become significant. The first problem is protecting the autos from damage due to flying debris and shock while in transit. The use of open cars with standard suspensions as presently used to transport new cars is limited, since reliance on preand post-transport inspection and servicing to remedy any damage is not practical in this respect.

Another problem involves that of integrating auto and passenger service, either by separate or by combination cars. If the latter is choosen, access to passenger sections and the degree of isolation between passenger section and the car storage section are factors.

Still another serious limitation on car design involves dimensions not only for the point of view of track clearances, but also from the point of view of dynamic stability of the train car in motion. Cars in which autos are carried with their lengths arranged transversely to the track have trouble with side clearance on existing rightof-ways. Cars built with multi-levels often have trouble, not only with overhead clearance, but also with top heaviness on curves.

Another consideration is the manner in which the autos are loaded and unloaded from the cars, especially in the case of multi-level cars. Because of the emphasis on simplicity of construction and low cost, the present most popular design is little more than the auto transporter mentioned above. These train cars load and unload through the ends, using external ramps. To use this equipment, the train cars must be disconnected, moved to a specially-designed loading area, and loaded carefully by skilled operators. The result is a lack of flexibility of use, and the introduction of considerable time delays.

Various more complex and more expensive alternatives to the traditional configuration have been suggested in the past. Most of these designs include a fairly complex self-contained elevator for lifting the cars from the lower to the upper level, and at least one design avoids the problems of end loading by using a selfcontained turntable to allow side loading (see patent to Demarest US. Pat. No. 2,146,203 issued Feb. 7, 1973). These alternatives are complex, costly and require skilled operation.

These and other difficulties experienced with the prior art devices have been obviated in a novel manner by the present invention.

It is, therefore, an outstanding object of the invention to provide a railroad car suitable for carrying both passengers and autos safely and conveniently.

Another object of this invention is the provision of a railroad car for carrying autos in which side access is made practical for standard gauge track, thereby eliminating the problems of end loading.

A further object of the present invention is the provision of a railroad car having several levels for carrying autos in which a simplified substitute for the auto elevator is provided.

It is another object of the instant invention to provide a railroad car which can be easily and quickly loaded and unloaded with autos without disconnecting the car from the train or for utilizing complex external equipment.

A still further object of the invention is the provision of a railroad car for the transportation of autos and passengers in which all areas outside of the passenger area are useable for storage of automobiles.

With these and other objects in view, as will be apparent to those skilled in the art, the invention resides in the combination of parts set forth in the specification and covered by the claims appended hereto.

SUMMARY OF THE INVENTION This invention involves a railroad car adapted to form one of a string of cars for transporting autos and passengers in a train, comprising an elongated bed supported on draft gear, first and second storage levels for a plurality of autos over the bed, and a lifting ramp for moving autos between the first level and the second level. More specifically, the lifting ramp is hingedly connected at one end to the second level, and the other end is movable between the first and second level. Access to the first level from the outside is through a side doorway with a drawbridge-type door.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring first to FIG. 2, wherein are best shown the general features of the present invention, the railroad car, indicated generally by the numeral 10, is shown as including an elongated bed Ill supported on draft gear such as dollies 12. A first deck 13 is mounted on the bed and a second deck I4 is supported over the first deck with a sheet metal skin I5 enclosing the decks. In this embodiment, the car shown is actually a symmetrical half of a larger structure connected and articulated at diaphragm 16. This half will be described as a sepa- 3 rate car. it being understood that the other half is its mirror image The" bed ll is about'eighty-one feet long andlow slung in the center. Each end has standard couples 17 and diaphragms. I v I i The first deck 13 generally follows the conto of the bed- 11, but with reduced slopes. The deck extends to each of the ends l8 and' 19 of the car. Each end of the car is provided with access doors 20 for passengers and sets of stairs 21 from deck 14'.

Midway down each-side of the car are doorways 22 (see FIG. 1) of about 6 feet 3 inches in height and 21 feet in width. The threshold of the doorways are at the level of the first deck 13. 1

Pivotally mountedat its lower edge ineach doorway 22,' is a door 23which can be lowered as a drawbridgetype loading ramp by means of cables'24 and a which 25 beneaththe second deck. 5

Supported above the first deck 13 is the second deck 1.4.- Thesecond deck 14 is divided into two parts; a car storage portion 26 and a passenger portion 27. The portions are separated from one another by two boxlike rooms 28 attached to the opposed walls (see FIG. 3). to form a narrow corridor between the portions.
