Abstract

A railroad open top hopper car comprises a pair of spaced trucks a railcar body, the body comprising a pair of side structures railcar, wherein each including (i) a top chord extending the side structure length, (ii) a plurality of upper side stakes extending from the top chord, (iii) an intermediate side chord extending the side structure length and below the top chord and coupled to the upper side stakes, (iv) a plurality of lower side stakes extending from the intermediate side chord, and (v) a side sill extending the length and below the intermediate side chord and coupled to the lower side stakes. The body forms discharge chutes forming pockets for the body with a plurality of intermediate doors and end doors, wherein the end doors are larger than the intermediate doors. Each door may include a biased door seal.

Claims (25)

1. A railroad open top hopper car comprising:

A pair of spaced trucks;

A railcar body supported on the trucks, the body comprising a pair of side structures on opposed sides of the railcar defining an interior hopper filled from above with lading, wherein each side structure includes a top chord extending the length of the side structure and a side sill extending the length of the side structure; and

A railroad car body bottom which forms a plurality of discharge chutes forming pockets for the body which open to the hopper interior with a plurality of intermediate doors and end doors for discharging lading from the interior hopper, wherein the end doors are positioned on end pockets and are larger than the intermediate doors, and wherein each door includes a biased door seal, with each door seal including a door seal member secured within a chamber for movement toward and away from a respective door, and a biasing member biasing the sealing member toward the door.

2. The railcar of claim 1 wherein the top chord has a top surface angled toward the interior of the hopper car so that lading landing on the top of the top chord will be directed by gravity toward the interior of the hopper.

3. The railcar of claim 2 wherein the top chord and side sill are formed of closed section aluminum extrusions.

4. The railcar of claim 3 further including a door operating mechanism operating on opposed sets of doors.

5. The railcar of claim 4 wherein the end doors are configures to provide an increased opening size of about 75% larger than the throat of the opening for the intermediate doors.

6. The railcar of claim 5 further including a contoured side structure construction of the side structures of the rail car.

7. The railcar of claim 6 wherein the top chord and side sill are formed of closed section aluminum extrusions.

8. The railcar of claim 7 further including a door operating mechanism operating on opposed sets of doors.

9. The railcar of claim 1 wherein the top chord and side sill are formed of closed section aluminum extrusions.

10. The railcar of claim 9 further including a door operating mechanism operating on opposed sets of doors.

11. The railcar of claim 1 further including a door operating mechanism operating on opposed sets of doors.

12. A railroad open top hopper car comprising:

A pair of spaced trucks;

A railcar body supported on the trucks, the body comprising a pair of side structures on opposed sides of the railcar defining an interior hopper filled from above with lading, wherein each side structure includes a top chord extending the length of the side structure and a side sill extending the length of the side structure; and

A railroad car body bottom which forms a plurality of discharge chutes forming pockets for the body which open to the interior hopper with a plurality of intermediate doors and end doors for discharging lading from the interior hopper, wherein each door includes a biased door seal, with each door seal including a door seal member secured within a chamber for movement toward and away from a respective door, and a biasing member biasing the sealing member toward the door.

13. The railcar of claim 12 further including a contoured side structure construction of the side structures of the rail car.

14. The railcar of claim 12 wherein the end doors are positioned on end pockets and are larger than the intermediate doors.

15. The railcar of claim 14 wherein the end doors are configures to provide an increased opening size of about 75% larger than the throat of the opening for the intermediate doors.

16. The railcar of claim 14 further including a top chord formed of closed section aluminum extrusions.

17. The railcar of claim 16 wherein the top chord has a top surface angled toward the interior of the hopper car so that lading landing on the top of the top chord will be directed by gravity toward the interior of the hopper.

18. The railcar of claim 12 further including a top chord formed of closed section aluminum extrusions.

19. The railcar of claim 18 wherein the top chord has a top surface angled toward the interior of the hopper car so that lading landing on the top of the top chord will be directed by gravity toward the interior of the hopper.
