A railcar body comprises at least one panel assembly having a first panel and a second panel, both extending longitudinally along the railcar body and adjacently to each other. The inner wall of the first and second panels, which are longer than their outer wall, respectively have at least a first and a second mating interface which are different from each other and compatible so as to be located at a predetermined distance from each other, thereby creating a gap of a predetermined width between two juxtaposed edges of the panels. This panel assembly is designed to be compatible with a laser welding process.

Systems and methods are provided herein for modifying a railcar to transport containerized proppant. Various examples are provided, including: stripping a rotary gondola railcar, stripping a gondola hopper railcar, installing or modifying a floor on a stripped railcar, installing container braces on a floor of a railcar, installing braces between the side walls of the railcar, installing struts between the side walls of the railcar using the beam of the container as a strut, creating a mold for foam reinforcement of a railcar, installing foam reinforcement in a railcar, and transporting a container of proppant using a modified railcar. Although these examples are described in relation to a coal railcar, they can be modified to use other types of railcars as well. These examples can also be combined together to form a method for modifying a railcar.

According to some embodiments, a system may include an additive manufacturing platform that provides additive manufacturing capability data. A customer platform, associated with a customer, may transmit an industrial asset item request for an industrial asset item. A digital transaction engine may receive the additive manufacturing capability data and the industrial asset item request. The digital transaction engine may then associate the industrial asset item request with an industrial asset definition file, and, based on the additive manufacturing capability data and the industrial asset definition file, assign the industrial asset item request to the additive manufacturing platform. The assignment of the industrial asset item request may be recorded via a secure, distributed transaction ledger. Responsive to the assignment, the additive manufacturing platform may create the industrial asset item (e.g., via an additive manufacturing printer) and provide the item to the customer.
