An American railroad industry term for a company or individual that manufactures railroad cars — freight wagons, passenger carriages, tank cars, and similar rolling stock. Carbuilders were a distinct trade from locomotive manufacturers and played a central role in 19th and early 20th-century American industrial expansion. The term appears in trade publications, industry directories, and historical railroad records. Today the function is largely handled by specialized manufacturers under different terminology.
The contract was awarded to a carbuilder in Ohio who had supplied boxcars to three major rail lines.
