An apparatus for securing railcar doors, comprising: a staple affixed to a portion of a railcar, wherein the staple defines a staple hole; and a hasp, comprising: a hinge;a first portion pivotally coupled to the hinge, the first portion affixed to the railcar; anda second portion, comprising a first end and a second end, wherein: the first end of the second portion is pivotally coupled to the hinge;the second end of the second portion is opposite the first end;the second portion of the hasp comprises a square key plug configured to be inserted into a square key hole of a railcar door, wherein the square key hole and square key plug each have a square cross-section, the square cross-section of the square key plug being smaller than the square cross-section of the square key hole;wherein:the second portion of the hasp defines a first hole through which a portion of the staple may pass when the hasp is in a closed position; anda side length of the square cross-section of the square key hole is less than √2 times bigger than a side length of the square cross-section of the square key plug. 2. The apparatus of claim 1, further comprising a locking mechanism configured to be placed through the defined staple hole when the hasp is in the closed position to prevent the hasp from opening. 3. The apparatus of claim 2, wherein the locking mechanism is one of a bolt seal and a padlock. 4. The apparatus of claim 1, wherein the staple and the first portion of the hasp are welded to a portion of a railcar. 5. The apparatus of claim 1, wherein the second portion of the hasp defines the first hole between the first end of the second portion of the hasp and the square key plug. 6. The apparatus of claim 1, wherein the second portion of the hasp defines the first hole between the square key plug and the second end of the second portion of the hasp. 7. The apparatus of claim l: further comprising a second staple; andwherein the second portion of the hasp defines a second hole through which a portion of the second staple may pass when the hasp in in a closed position. 8. The apparatus of claim 7, wherein: the second portion of the hasp defines the first hole between the first end of the second portion of the hasp and the square key plug; andthe second portion of the hasp defines the second hole between the square key plug and the second end of the second portion of the hasp. 9. A method for securing railcar doors, comprising affixing a staple to a portion of a railcar;providing a square key plug configured to be inserted into a square key hole of the railcar, wherein the square key hole and square key plug each have a square cross-section, the square cross-section of the square key plug being smaller that the square cross-section of the square key hole;providing a hasp, wherein the hasp comprises: a hinge;a first portion pivotally coupled to the hinge;a second portion, comprising: first end pivotally coupled to the hinge;a second end;wherein the second portion of the hasp defines a first hole through which a portion of the staple may be disposed;wherein the provided square key plug is affixed to the second portion of the hasp; andaffixing the first portion of the hasp to the railcar such that when the hasp is closed, the square key plug is inserted within the square key hole of the railcar and a portion of the staple is disposed through the first hole defined in the second portion of the hasp;wherein a side length of the square cross-section of the square key home is less than √2 times bigger than a side length og the square cross-section of the square key plug. 10. The method of claim 9, wherein the first portion of the hasp is affixed to the railcar above the square key hole of the railcar. 11. The method of claim 9, wherein affixing the staple and the first portion of the hasp comprises welding each of the staple and the first portion of the hasp to a portion of the railcar. 12. The method of claim 9, wherein the square key plug is affixed to the second portion of the hasp between the second end of the second portion of the hasp and the hole defined by the second portion of the hasp. 13. The method of claim 9, wherein the square key plug is affixed to the second portion of the hasp between the first end of the second portion of the hasp and the hole defined by the second portion of the hasp. 14. The method of claim 9: further comprising affixing a second staple to a portion of a railcar; andwherein the second portion of the hasp defines a second hole through which a portion of the second staple may pass when the hasp in in a closed position. 15. The method of claim 14, wherein the square key plug is affixed to a portion of the second portion of the hasp between the first hole and the second hole. 16. An apparatus, comprising: at least one railcar door, the at least one railcar door comprising a locking mechanism, the locking mechanism comprising a square key hole, the locking mechanism coupled to at least one locking pin;a staple affixed to a portion of the at least one railcar door, wherein the staple defines a staple hole; anda hasp, comprising: a hinge;a first portion pivotally coupled to the hinge, the first portion affixed to the railcar; anda second portion, comprising a first end and a second end, wherein: the first end of the second portion is pivotally coupled to the hinge; the second end of the second portion is opposite the first end; andthe second portion of the hasp comprises a square key plug configured to be inserted into the square key hole afire at least one railcar door, wherein the square key hole and square plug each have a square cross-section, the square cross-section of the square key plug being smaller than the square cross-section of the square key hole;wherein:the second portion of the hasp defines a first hole through which a portion of the staple may pass when the hasp is in a closed position: anda side length of the square cross-section of the square key hole is less than √2 times bigger than a side length og the square cross-section of the square key plug. 17.
