The railcar door assembly of claim 1 wherein each of said first and second pawls has first and second ends with said first ends continuously urged toward engagement with said ratchet wheel. 8. The railcar door assembly of claim 7 wherein the second end of each pawl has a greater weight than its respective first end so that said pawls are continuously urged to pivot around said pivot pin toward engagement with said ratchet wheel. 9. The railcar door assembly of claim 1 further including a second ratchet wheel having a plurality of teeth extending generally radially outward from the outer circumference thereof and mounted to said railcar door in spaced relation to said first ratchet wheel. 10. The railcar door assembly of claim 9 wherein a third pawl is disposed for selective operative engagement with said second ratchet wheel teeth for selectively preventing undesired movement of said second ratchet wheel in one direction of rotation. 11. The railcar door assembly of claim 10, wherein said third pawl has a first end and a second end, said third pawl first end including a portion for selective engagement with said second ratchet wheel teeth. 12. The railcar door assembly of claim 10, wherein said third pawl is mounted in spaced relation to said first and second pawls on a common pivot pin. 13. A railcar door assembly comprising: a substantially planar door; at least one elongated support member rotatable mounted to said door; a drive mechanism associated with said door and operatively connected to said support member for selectively rotating said support member about its length to partially open or fully close said door; and, a stop mechanism associated with said door for preventing movement of said drive mechanism when said door is in one of a partially opened and fully closed position, said stop mechanism including a first rotatable mounted ratchet wheel and first and second pawls disposed in a side-by-side relation for selective alternating engagement with said ratchet wheel to selectively prevent movement of said ratchet wheel in one direction of rotation; and, wherein each of said pawls includes a grooved area extending to the pawl outer extremity from a pivot pin mounting opening for preventing debris buildup between said pawls and said pivot pin. 14. A stop mechanism for a railcar door having a gear mechanism and a lever operatively connected thereto for rotating the gear mechanism to open and close the door, said stop mechanism comprising: a ratchet wheel having a plurality of teeth extending generally radially from the outer circumference thereof and adapted for rotatable mounting to said railcar door; a first pawl disposed for selective operative engagement with said ratchet wheel teeth; a second pawl disposed for selective operative engagement with said ratchet wheel teeth; and, said first and second pawls being configured and dimensioned so that one of said pawls is always disposed in operative engagement with one of said ratchet wheel teeth for selectively preventing undesired movement of said ratchet wheel in one direction of rotation; wherein each of said first and second bawls has first and second ends, said first ends each including a portion for selective engagement with said ratchet wheel teeth; and, said first and second pawls being mounted in side-by-side relation on a common pivot pin and wherein said first ends of said pawls are configured and dimensioned such that when the first end portion of one pawl is in engagement with a ratchet wheel tooth the first end portion of the other pawl is disengaged from said ratchet wheel teeth. 15. The stop mechanism of claim 14 wherein each of said ratchet wheel teeth has a leading edge and a trailing edge, said fir
