Description
Railroad Short Name: DRGW
The “committee design” car refers to a family of cars whose design specifications were set forth by Norfolk & Western, Chesapeake & Ohio and Pennsylvania Railroads. It is one of the most prolific hoppers ever constructed, and it has a rich history. Depending on how one tells its story, the committee design hopper will mean different things to different people. It is one of the largest, single classes of freight car (of any type) to ever be constructed, and simultaneously, it represents a failure for cooperating railroads to standardize around a single design.
Arrowhead has produced two distinct sets of body tooling to accurately match the distinct car variations of the PRR Pullman-Standard 666000-666999 series, D&RGW Bethlehem Car Co. 14600-14999 series, and Southern Bethlehem Car Co. 74689-74758 series cars.
