Abstract: A sand car modification program including removing a center section at cut-lines between the trucks and maintaining two repurposed end sections for the modified railcar. Each end section including a center sill section, side sill sections; top chord sections, side wall sections, and a sloped end floor section extending between the pair of side wall sections and extending down at least to the pair of side sill sections. An underframe construction of the modified railcar is formed between the repurposed end sections, including a center sill construction coupled to the end section center sill sections, a plurality of hopper gate openings, and at least one hopper divider. A pair of sidewall constructions are formed between the end sections, each including a side sill section, a top chord section, and a side wall section.

Abstract: A railroad coupler knuckler meets AAR contour requirements and it includes unique external weight reducing features that strategically reduce weight without compromising strength or fatigue life. The design of the railroad knuckle of the present invention allows for formation of the knuckle through forging or coreless casting techniques and thus allows for the use of a better grade of steel compared to AAR Grade E and such forged or cast knuckle will yield much higher fatigue life compared to cast knuckles.
