A railcar coupler knuckle comprising:
- a C-10 pin hole;
- a top knuckle pulling lug;
- wherein interior spaces of the railcar coupler knuckle are formed using a core comprising:
- a contoured surface configured to provide detail to the interior spaces of the railcar coupler knuckle;
- and
- wherein the railcar coupler knuckle has a wall thickness that has a substantially constant thickness over a majority of the distance from a top of a front face of the top knuckle pulling lug to a bottom face of the top knuckle pulling lug.

A railcar coupler knuckle comprising:
- a C-10 pin hole;
- a top knuckle pulling lug;
- wherein interior spaces of the railcar coupler knuckle are formed using a core comprising:
- a rear core support configured to support the core when the core is assembled in a mold used to cast the railcar coupler knuckle;
- a contoured surface configured to provide detail to the interior spaces of the railcar coupler knuckle;
- and
- a parting line defined on the contoured surface and extending from the rear core support to the C-10 portion.
- wherein the railcar coupler knuckle has a wall thickness from the top of a front face of the top knuckle pulling lug to a bottom face of the top knuckle pulling lug.

A core assembly for forming interior spaces of a railcar coupler knuckle, the core comprising:
- a first portion, the first portion comprising:
- a C-10 portion configured to form the C-10 pin hole in the railcar coupler knuckle;
- a rear core support configured to support the core when the core is assembled in a mold used to cast the railcar coupler knuckle;
- a contoured surface configured to provide detail to the interior spaces of the railcar coupler knuckle;
- and
- a second portion, the second portion configured to form internal spaces in a front face side in the railcar coupler knuckle
- wherein the first portion is shaped such that the railcar coupler knuckle has a wall thickness from a top of a front face of a top knuckle pulling lug to a bottom face of the top knuckle pulling lug.
